''Aequidens'' is a South American genus of fish in the family Cichlidae. Many species formerly placed in this genus have been reallocated to other genera such as ''Andinoacara'', ''Bujurquina'', ''Laetacara'', ''Tahuantinsuyoa'', ''Krobia'', ''Rondonacara'' and ''Cleithracara''.〔Ottoni, F.P. & Mattos, J.L.O.

''Vertebrate Zoology, 65 (1): 65-79.''〕 As presently defined, ''Aequidens'' is largely restricted to the Amazon Basin, Orinoco Basin and river basins in The Guianas. The only exceptions are ''A. plagiozonatus'' which also occurs in the Paraná Basin, and ''A. tetramerus'' which also occurs in the Parnaíba River. ==Species== There are currently 16 recognized species in this genus:〔Musilová, Z., Říčan, O. & Novák, J.
