花冠芋螺（学名：Conus coronatus），是新腹足目芋螺科芋螺属的一种。主要分布于马来西亚、印度尼西亚、中国大陆、**，常栖息在潮间带珊瑚礁、潮下带。

Conus coronatus, common name the crowned cone or the coronated cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.

Like all species within the genus Conus, these snails are predatory and venomous. They are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.
