Labrisomids are small blennioids (blennies), perciform marine fish belonging to the family Labrisomidae. Found mostly in the tropical Atlantic and Pacific Ocean, the family contains about 110 species in 15 genera.

Stockier than the average blenny, labrisomids are elongated nonetheless; their dorsal fin spines outnumber soft rays (which may be absent altogether), and their pelvic fins are long and slender. Like many other blennies, labrisomids have whisker-like structures called cirri on their heads and napes. Scales may be cycloid or absent in labrisomids; many species are brightly coloured. The hairy blenny (Labrisomus nuchipinnis) is the largest species at 23 cm in length; most are far smaller.
