Geophagus sveni is a Geophagini cichlid native to the Tocantins River drainage in Brazil. Geophagus sveni is a medium-sized cichlid that reaches approximately 225 mm (10 in) in standard length (SL), and is usually found in the Tocantins River basin. Similarly, Geophagus sveni has a typical teleost encephalon, without significant intraspecific variation and hence without dimorphic traits.

The fish is named in honor of Sven O. Kullander of the Swedish Museum of Natural History, for his many contributions to cichlid systematics.
