花锦芋螺（学名：Conus legatus），是新腹足目芋螺科芋螺属的一种。主要分布于中国大陆、台湾，常栖息在潮下带。

Conus legatus, common name the ambassador 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.
