The yellow-headed temple turtle (Heosemys annandalii) is a large species of turtle in the family Geoemydidae. The species is native to Southeast Asia.
The common name, "yellow-headed temple turtle", is derived from the fact that it is often found near Buddhist temples within its range.
The specific name, annandalii, is in honor of Scottish herpetologist Nelson Annandale.
H. annandalii may grow to over 20 in (51 cm) in straight carapace length.
H. annandalii is aquatic, and is generally herbivorous.
