The admiral cone (Conus ammiralis) is a marine gastropod mollusk in the family Conidae, a group of sea snails. As with all members of the genus Conus, it is a predatory and venomous species. Its sting can harm humans, so live specimens should be handled with great caution or avoided entirely. The shell ranges from 35 mm to 109 mm in length.

Its color is chestnut, marked with darker revolving lines, and features upper, basal, and one or two approximate bands that are finely reticulated with yellow on a white background. Large, irregularly placed triangular white spots overlay this pattern. This species is found in the Red Sea and the Mascarenes, as well as across the Indo-West Pacific, including Fiji, Indo-China, Indo-Malaysia, the Marshall Islands, New Caledonia, the Solomon Islands, Thailand, Vanuatu, and parts of Australia (Northern Territory, Queensland, and Western Australia).
