Bothremydidae is an extinct family of side-necked turtles. They belong to suborder Pleurodira and the order Testudines. Like their modern relatives, bothremydidids often inhabited freshwater, but several species were instead marine; they are unrelated to modern sea turtles. They were actively mobile omnivores. They became extinct in the Late Eocene. The family is split into two subfamilies and a number of tribes. Bothremydidae
