binomial_authority =Fei, Ye & Huang, 1991The Huanren frog, "Rana huanrenensis", is a species of true frog found in East Asia. It was originally believed to be endemic to Huanren in China, but was later also found in South Korea; it is presumed to be present in North Korea as well. It is closely related to the Dybowski's frog, "Rana dybowskii", and specimens collected before 1991 were incorrectly identified as that species. Distinguishing factors include the absence of a vocal sac.

The Huanren frog is found in and around rivers and streams in hilly terrain. The type locality in Huanren is 520 meters above sea level, and specimens from Korea have also only been found at altitudes over 500 m. Specimens from South Korea have been collected in Gangwon, Gyeongbuk, and eastern Gyeonggi provinces. Egg clutches, which are small and clustered, are deposited on submerged rocks in the streams which this species favors.
