Mose Janashvili (Georgian: ???? ?????????) (March 19, 1855 – April 19, 1934) was a Georgian historian, ethnographer, and linguist.
He was born into a Georgian Ingilo community at Qakh (now Azerbaijan).
Educated at Tbilisi and Kutaisi, he worked as a teacher for several years, from 1875 to 1920, and later served as a professor at the Tbilisi State University.
He mostly engaged in study of medieval Georgian chronicles and hagiographic literature.
As a linguist, Janashvili subscribed to the theory that linked Georgian with the Indo-European languages.
