Barbour's map turtle (Graptemys barbouri) is a species of turtle in the family Emydidae. The species is native to the southeastern United States.
The specific name or epithet, barbouri, is in honor of American herpetologist Thomas Barbour.
Adult male Barbour's map turtles are on average 3.5 to 5.5 in (9–14 cm) in straight-line carapace length. Adult females are much larger and can vary from 6 to 12.5 in (15 – 32 cm) in straight-line carapace length. "Females attain really imposing dimensions, and their heads are enormously enlarged". G. barbouri possesses black-tipped spines on the second, third, and fourth vertebral scutes. These spines are very noticeable in males, and resemble a dorsal fin.
Barbour's map turtle mainly consumes mollusks, insects, and small fish found in rivers.
