Buyeo or Fuyu languages (부여 in Korean, Fúyú (扶餘) in Chinese) are a hypothetical language family that consists of ancient languages of the northern Korean Peninsula, southern Manchuria and possibly Japan. According to Chinese records, the languages of Buyeo, Goguryeo, Dongye, Okjeo, Baekje—and possibly Gojoseon—were similar. Ye-Maek may have been ancestral.
