Fundulidae is the family of topminnows and (mainly) North American . The 46 species are native to North America as far south as Yucatan, and to the islands of Bermuda and Cuba, occurring in both freshwater and marine environments.

Members of the family are all small; while the giant killifish Fundulus grandissimus and northern studfish Fundulus catenatus reach 20 cm in length, but most species are under 10 cm.

The distinguishing characteristic of the family is the maxillary bone, which is twisted instead of being straight.
