Quasipaa delacouri (common names: Doi Chang Asian frog, Tonkin Asian frog) is a species of frog in the Dicroglossidae family. Based on its known distribution, it is endemic to northern Vietnam, although it is considered likely that it also occurs in adjacent Laos and China.This poorly known species is presumed to be associated with small streams (its habitat in the Tam Đảo National Park). Possible threats include collection for human consumption and habitat loss.
