The Manchurian pika (Ochotona mantchurica) is a species of mammal in the family Ochotonidae. It is found in the mountains of northeastern China in Inner Mongolia, specifically the Lesser and Greater Khingan ranges, as well as parts of Zabaykalsky Krai. It is rated as a species of least concern on the International Union for Conservation of Nature Red List of Endangered Species.
The Manchurian pika was originally divided into different classifications based on its populations' distribution, with those in Russia described as alpine pikas (O. alpina) and those elsewhere (which make up most of the nominative form) described as northern pikas (O. hyperborea). The species is on a whole closely related to both the northern pika and Hoffmann's pika (O. hoffmanni). It is separated from the former despite their nearly-overlapping distributions by its large skull, relative to other pikas.
Three subspecies have been identified:
