The red-crowned roofed turtle (Batagur kachuga) is a species of freshwater turtle endemic to South Asia.
It was the type species of its former genus Kachuga.
Females can grow to a shell length of 56 cm (22 in) and weigh 25 kilograms (55 lb), but males are considerably smaller.
The turtles like to bask in the sun on land.
In the breeding season, the heads and necks of male turtles exhibit bright red, yellow and blue coloration.
The females excavate nests in which they lay clutches of up to thirty eggs.

Historically, this turtle was found in central Nepal, northeastern India, Bangladesh and probably Burma, but it has suffered declines in population due to being harvested for meat and shells, drowned in fishing nets, water pollution, hydro-electric schemes and habitat loss.
Fewer than four hundred adult females are thought to remain in the wild, with the International Union for Conservation of Nature rating this turtle as being "critically endangered".
India has put conservation measures in place, and a captive breeding programme has been initiated.
