Leptolalax bourreti (Bourret's Asian toad or Bourret litter frog) is a frog species in the family Megophryidae. It is known with certainty only from the vicinity of its type locality in Sa Pa in northern Vietnam. Earlier records from Laos refer to Leptolalax eos (described in 2011) and those from Thailand probably to an unnamed species. Its natural habitats are subtropical moist lowland forests, moist montane forests, and rivers. Its status is insufficiently known.
