Frogfishes are a family, Antennariidae, of anglerfishes. They are found in tropical oceans and seas around the world.

They are small fishes with large globose heads. They can be distinguished from other anglerfishes by the three extended dorsal fin spines on their heads. They are mostly bottom-dwelling fishes that are well camouflaged; they employ the first dorsal spine as a fishing lure to attract prey.

The sargassumfish, Histrio histrio, is unique among frogfishes in that it clings to floating Sargassum weed.
