The lagoon triggerfish (Rhinecanthus aculeatus), also known as the blackbar triggerfish, the Picasso triggerfish, the Picassofish, and the Jamal, is a triggerfish, up to 30 cm in length, found on reefs in the Indo-Pacific region.

The Hawaiian name for the fish, humuhumunukunukuāpuaʻa (pronounced [ˈhumuˈhumuˈnukuˈnukuˈwaːpuˈwɐʔə]), also spelled humuhumu-nukunuku-a-puaʻa or just humuhumu for short (meaning "triggerfish with a snout like a pig") shares the same name with the reef triggerfish, the state fish of Hawaii.
