Martine Irma Robbeets (24 October 1972) is a Belgian comparative linguist and japanologist. She is known for the Transeurasian languages hypothesis, which groups the Japonic, Koreanic, Tungusic, Mongolic, and Turkic languages together into a single language family.

Robbeets received a Ph.D. in Comparative Linguistics from Leiden University, and also received a master's degree in Korean studies from Leiden University. She also holds a master's degree in Japanese studies from KU Leuven.

In addition to being a lecturer at the University of Mainz, she is also a group leader at the Max Planck Institute for the Science of Human History in Jena, Germany.^[2]

In 2017, Robbeets proposed that Japanese (and possibly Korean) originated as a hybrid language. She proposed that the ancestral home of the Turkic, Mongolic, and Tungusic languages was somewhere in northwestern Manchuria. A group of those proto-Altaic ("Transeurasian") speakers would have migrated south into the modern Liaoning province, where they would have been mostly assimilated by an agricultural community with an Austronesian-like language. The fusion of the two languages would have resulted in proto-Japanese and proto-Korean.^[3][4]

In 2018, Robbeets and Bouckaert used Bayesian phylolinguistic methods to argue for the coherence of the Altaic languages, which they refer to as the Transeurasian languages.^[5]
