Lucania is a genus of North American ray-finned killifishes in the family Fundulidae. It can be found in northeastern Mexico and the southeastern and eastern parts of the United States, with Lucania parva ranging as far north as Massachusetts. Adult specimens of this genus range from 2.9 to 6.0 centimetres (1.1 to 2.4 inches) in length. All species are oviparous and can live in fresh water, though L. parva - in spite of its name 'rainwater killifish' - is more typically a coastal fish found in salt or brackish water. L. goodei and L. parva are sometimes kept in aquariums, where they are considered hardy, adaptable aquarium residents.
There are currently three recognized species in this genus:
