Oreolalax weigoldi, also known as Weigold's lazy toad or Weigold's toothed toad, is a species of amphibian in the family Megophryidae. It is endemic to Sichuan, China. It is only known from its type locality, Washan in southern Sichuan; there are, however, many places with this name in Sichuan. It might be the same species as Oreolalax major <small>(Liu and Hu, 1960)</small>.
The single male specimen (holotype) was in snout-vent length.
