The wood turtle is a species of turtle endemic to North America. It is in the genus Glyptemys, a genus which contains only one other species of turtle: the bog turtle. The wood turtle reaches a straight carapace length of 14 to 20 centimeters, its defining characteristic being the pyramidal shape of the scutes on its upper shell. Morphologically, it is similar to the bog turtle, spotted turtle, and Blanding's turtle. The wood turtle exists in a broad geographic range extending from Nova Scotia in the north to Minnesota in the west and Virginia in the south. In the past, it was forced south by encroaching glaciers: skeletal remains have been found as far south as Georgia.

Glyptemys is a genus of turtles in the family Emydidae. It comprises two species, the bog turtle and wood turtle, both of which are endemic to North America. Until 2001, these turtles were considered members of the genus Clemmys, which currently has one member, the spotted turtle.
