The Goguryeo language was spoken in the ancient kingdom of Goguryeo (37 BCE – 668 CE), one of the Three Kingdoms of Korea. The language is also known as Old Koguryo, Koguryoic, and Koguryoan.

It is unknown except for a small number of words, which mostly suggest that it was similar but not identical to the language of Silla, and may have been influenced by the Tungusic languages. Striking similarities between Baekje and Goguryeo can also be found, which is consistent with the legends that describe Baekje being founded by the sons of Goguryeo's founder. The Goguryeo names for government posts are mostly similar to those of Baekje and Silla.

Chinese records suggest that the languages of Goguryeo, Buyeo, Eastern Okjeo, Baekje, Silla, and Gojoseon were similar, while the language of Malgal (Mohe) in Manchuria differed significantly.

Alexander Vovin argued that the connections to Japanese may be due to earlier languages of southern Korea, such as perhaps Gaya, and that Goguryeo–Baekje was closer to Silla and Korean. Words of Goguryeo origin can be found in Middle Korean (early 10th to late 14th century). Christopher I. Beckwith attempted to link Buyeo, Goguryeo, and Baekje with Old Japanese. As a minority theory, Finnish linguist Juha Janhunen believes that it was likely that a "Tungusic-speaking elite" ruled Goguryeo and Balhae, describing them as "protohistorical Manchurian states" and that part of their population was Tungusic, and that the area of southern Manchuria was the origin of Tungusic peoples and inhabited continuously by them since ancient times, and Janhunen rejected opposing theories of Goguryeo and Balhae's ethnic composition.
