The Isthmian mouse opossum (''Marmosa isthmica'') is a species of opossum in the family Didelphidae found in Colombia, Ecuador, and Panama.Fiona A. Reid, ''A field guide to the mammals of Central America & Southeast Mexico'' (OUP USA, 2009)

Foraging along branches and vines for fruit and insects, with the help of a prehensile tail, ''M. isthmica'' was formerly considered a subspecies of Robinson's mouse opossum (''Marmosa robinsoni'') and is supposed to be similar to it in habit, but following Rossi (2005) it is now deemed a species.

In 1935 in the Panama Canal Zone, Enders observed ''Marmosa isthmica'' to build nests with leaves in a nestbox fixed to a tree.Papéis Avulsos de Zoologia: vol. 41 (1999), Issues 1-14, p. 177
