The spotted bass (Micropterus punctulatus), also called spotty, or spots in various fishing communities, is a species of North American freshwater fish belonging to the sunfish family (Centrarchidae) of the order Centrarchiformes. It is noted for the rows of dark spots below the lateral line, which give it its common name. One of the black basses, it is native to the Mississippi River basin and across the Gulf states, from central Texas through the Florida panhandle. Its native range extends into the western Mid-Atlantic states and it has been introduced into western North Carolina and Virginia. It has also been introduced to southern Africa, where it has become established in some isolated waters as an invasive species.

Spotted bass can reach an overall length of almost 64 cm (25 in), and can weigh up to 5.2 kg (11 lb). It can live to an age of at least seven years. Preferring cool and warm mountain streams and reservoirs with rocky bottoms, the spotted bass feeds on insects, crustaceans, frogs, annelid worms and smaller fish. It is often mistaken for the similar and more common largemouth bass. A convenient way to distinguish between a largemouth and a spotted bass is by the size of the mouth. A spotted bass will resemble a largemouth bass in coloration but will have a smaller mouth.

In 2010, the scientific community officially recognized a separate subspecies of spotted bass, native to the Tallapoosa and Coosa Rivers and their lakes. This species is commonly known as the Alabama spotted bass (M. henshalli) and known locally as the "Coosa spotted bass", not to be confused with the redeye Coosa bass found in north Georgia. The Alabama spotted bass is highly prized as a gamefish and average size is much larger than the more common Kentucky spotted bass. The current record spotted bass, caught in Pine Flat Lake in California, weighed 10.27 lb (4.66 kg).
