Cagayan de Oro
Highly urbanized city and regional hub of Northern Mindanao.
Cagayan de Oro (often called CDO) is a highly urbanized city in the Philippines, located on the north-central coast of Mindanao along Macajalar Bay. As of the 2024 census, its population is 741,617, making it the 10th most populous city in the country and the most populous in Northern Mindanao. It is the capital of Misamis Oriental province, where it is geographically situated and grouped by the Philippine Statistics Authority, but it is governed independently from the provincial government. CDO also functions as the regional center and business hub of Northern Mindanao, and it anchors the growing Metropolitan Cagayan de Oro area, which includes the city of El Salvador and the towns of Opol, Alubijid, Laguindingan, Gitagum, Lugait, Naawan, Initao, Libertad, and Manticao to the west, and Tagoloan, Villanueva, Jasaan, Claveria, and Balingasag to the east. The city is bordered by Opol to the west, Tagoloan to the east, and the provinces of Bukidnon and Lanao del Norte to the south. It is well known for white water rafting and kayaking on the Cagayan de Oro River.
**Etymology**
The name "Cagayan de Oro" translates to "River of Gold." It traces back to the arrival of Spanish Augustinian Recollect friars in 1622, when the area around Himologan (now Huluga) was already called "Cagayán." Sixteenth-century Spanish documents also used this name. Variations of the word—karayan, kayan, kahayan, kayayan, kagayan, and kalayan—all mean "river." The region, including Cagayan de Oro, was granted as an encomienda to Don Juan Griego on January 25, 1571. Former Vice President of the Philippines Emmanuel Peláez later added "de Oro" to the name. The name "Cagayan" is shared by other places in the Philippines, such as the province of Cagayan in Cagayan Valley (northern Luzon), which has a similar reference to its river, the Cagayan Islands in the northern Sulu Sea, and the former Cagayan de Sulu (now Mapun) in Tawi-Tawi.
**History**
**Prehistoric Period**
The Cagayan de Oro area was continuously inhabited by Late Neolithic to Iron Age Austronesian cultures. The oldest human remains found come from the Huluga Caves, once used as a burial site. A skullcap sent to the Scripps Institution of Oceanography in 1977 was dated to between 350 and 377 AD. The caves have yielded many artifacts, but most areas have been badly damaged by guano collectors and amateur treasure hunters. Associated with the caves is the Huluga Open Site, believed to be the location of the primary pre-colonial settlement called "Himologan" by early Spanish missionaries. It lies about eight kilometers from present-day Cagayan de Oro.
**Early Historic Period**
In 2009, a grave site was discovered containing Song dynasty (960–1279 AD) celadon ware and Sukhothai period (1238–1347 AD) Sangkhalok ceramic ware, along with body ornaments and stone tools. This shows the region was part of an ancient maritime trading network in Southeast Asia. Skulls from the site indicate that native Kagay-anons practiced artificial cranial deformation from childhood as a mark of social status, similar to skulls from archaeological sites in nearby Butuan. The Huluga Open Site was extensively damaged in 2001 to make way for a bridge project by the local administration. It became controversial when a team from the University of the Philippines-Archaeological Studies Program dismissed its archaeological importance, calling it a "camp-like area" rather than a settlement, and therefore not worthy of heritage protection. Local conservationists alleged the UP-ASP team was influenced by the local government to allow the bridge project to proceed. The site remains unprotected and continues to be quarried, despite protests from local historians and archaeologists.
**Colonial Period**
**Spanish Period**
The Himologan settlement was still occupied when Europeans made contact. In 1622, two Spanish Augustinian Recollect missionaries reached it and described inhabitants as a mixed stock descended from Lumad and sea-faring Visayans ("Dumagat"). The men were tattooed like other Visayans, and the women wore intricate jewelry, some of gold. The people were animists practicing traditional anitism, though they paid tribute to Muhammad Kudarat, the sultan of the Islamized Sultanate of Maguindanao. The original Lumad inhabitants of Cagayan de Oro and Misamis Oriental are the Higaonon people, whose name means "people of the coast" (from *higa*, meaning "coastal plain" or "shore"). They resisted Spanish Reducciones policies and were displaced by incoming Dumagat migrants (mostly Visayans) during the Spanish colonial period, moving to the interior highlands of Misamis Oriental and northern Bukidnon. In 1626, Fray Agustín de San Pedro persuaded the chief of Himologan, Datu Salangsang, to move his settlement down the Cagayan River to what is now Gaston Park. De San Pedro later fortified the new settlement against Sultan Kudarat's raiders. Spanish dominance was established in 1738. When Misamis became a province in 1818, one of its four districts was the Partidos de Cagayan. In 1871, the "Partidos" became a town.
Lore & Background
The area around Cagayan de Oro was continuously inhabited from the Late Neolithic to Iron Age. The oldest human remains from the Huluga Caves have been dated, but these dates are disputed and not widely accepted as established canon. The settlement was inhabited by a mixed Lumad and Visayan population, practicing animism and paying tribute to Sultan Muhammad Kudarat of Maguindanao. The name 'Cagayan' (meaning river) was already in use by the 16th century; 'de Oro' was officially adopted in 1950 by Republic Act No.
Reader's Guide
Cagayan de Oro's significance lies in its long history as a settlement and its evolution into a major urban center. Pre-colonial trade is evidenced by Song dynasty and Sukhothai ceramic ware found in graves. During the Spanish period, it became the capital of Misamis and a seat of Spanish government in Mindanao. In the Philippine–American War, local forces under Col. Apolinar Velez achieved the Americans' first defeat at the Battle of Makahambus Hill on June 4. Today, Cagayan de Oro is the most populous city in Northern Mindanao, a regional economic hub, and known for white water rafting. The Huluga Open Site remains unprotected and continues to be quarried despite protests.

Urban Heart of Northern Mindanao
Though geographically nestled within Misamis Oriental and grouped under that province by the Philippine Statistics Authority, it operates as a highly urbanized city with full administrative independence from provincial governance. Its role extends well beyond its own borders: CDO functions as the regional business hub and administrative center for all of Northern Mindanao. The city anchors the expanding Metropolitan Cagayan de Oro corridor, which stretches westward to include El Salvador, Opol, Alubijid, Laguindingan, Gitagum, Lugait, Naawan, Initao, Libertad, and Manticao, and eastward to Tagoloan, Villanueva, Jasaan, Claveria, and Balingasag. Situated on the north-central coast of Mindanao facing Macajalar Bay, the city is flanked by Opol to the west, Tagoloan to the east, and the provinces of Bukidnon and Lanao del Norte to the south. Beyond its administrative weight, CDO has also cultivated a tourism identity, particularly through white-water rafting and kayaking adventures along the Cagayan de Oro River.
A Name Written in Gold and River
The name Cagayan de Oro, literally "River of Gold," carries layers of linguistic and political history. The root word "Cagayan" simply means river, appearing in numerous pre-colonial spellings—karayan, kayan, kahayan, kayayan, kagayan, and kalayan—all of which denote the same natural feature. Early sixteenth-century Spanish documents already used the term "Cagayán" to describe the area around what is now Huluga. It was not until later that former Vice President Emmanuel Peláez appended "de Oro" to the river's name, giving the city its full and evocative title. The word "Cagayan" is not unique to Mindanao; it also names a province in Cagayan Valley on northern Luzon, the Cagayan Islands in the northern Sulu Sea, and the former Cagayan de Sulu, now called Mapun, in Tawi-Tawi. Each of these places shares the same river-root, underscoring how deeply the concept of a great waterway is woven into Filipino geographic identity.
Ancient Waters, Ancient People
Long before any European ship reached Mindanao's shores, the Cagayan de Oro area hosted continuous human habitation from the Late Neolithic through the Iron Age. A 2009 grave-site excavation uncovered Song dynasty celadon ware and Sukhothai-period Sangkhalok ceramics alongside body ornaments and stone tools, revealing the region's participation in ancient Southeast Asian maritime trade networks. Skulls recovered there also show evidence of artificial cranial deformation practiced from childhood as a social-status marker, a custom paralleled in neighboring Butuan. The associated Huluga Open Site, identified by early Spanish missionaries as "Himologan," was believed to be the primary pre-colonial settlement in the region. Tragically, the site was extensively damaged in 2001 to clear ground for a bridge project, sparking fierce controversy after a University of the Philippines archaeological team dismissed its importance as merely a "camp-like area." Local conservationists alleged the assessment was politically motivated, and the site remains unprotected, continuing to be quarried despite ongoing protests from historians and archaeologists.
From Himologan to the Colonial Capital
The men bore Visayan-style tattoos, the women wore intricate golden jewelry, and the people practiced anitism while paying tribute to Sultan Muhammad Kudarat of Maguindanao. The original Lumad inhabitants, the Higaonon—whose name translates to "people of the coast"—resisted Spanish Reducciones policies and were gradually displaced by incoming Dumagat migrants, many retreating to the interior highlands of Misamis Oriental and northern Bukidnon. Spanish control deepened over the following decades.
