Scotinomys is a genus of rodent, the singing mice, in the family Cricetidae.{{MSW3 Muroidea | id = 13000518 | pages = 1085–1086 | heading = Genus Scotinomys}} Together with Baiomys, it forms the tribe Baiomyini.

It contains the following species:

• Alston's brown mouse (Scotinomys teguina)
• Chiriqui brown mouse (Scotinomys xerampelinus)

They are found in mountainous areas in Central America, at altitudes of 1000 m to at least 3500 m.Hooper, E. T. (1972). A synopsis of the rodent genus Scotinomys. Occasional Papers of the Museum of Zoology, University of Michigan, 665, 1-13.[https://deepblue.lib.umich.edu/handle/2027] As their common name indicates, they are notable for their acoustic communication. They are insectivorous. The two species show substantial divergence in behaviour and reproduction,Hooper, E. T., & Carleton, M. D. (1976).
