Bairdemys is an extinct genus of side-necked turtles in the family Podocnemididae.

The genus was described in 2002 by Gaffney & Wood and the type species is B. hartsteini.

Bairdemys belonged to the Stereogenyini, a tribe of the subfamily Erymnochelyinae that had adapted to coastal marine habitats and was successful from the late Oligocene through much of the Neogene.

This tribe was primarily diverse along the coastlines of the Tethys (and later Indian) ocean of Africa and Asia, with Bairdemys being the only genus inhabiting the coastlines of the western Atlantic Ocean along the Americas.

The separation between the Afro-Asian Stereogenyita and the American Bairdemydita (containing only Bairdemys) appears to have occurred at the start of the Late Oligocene.
