Achille Emile Meeussen, also spelled Achiel Emiel Meeussen, or simply A.E. Meeussen (as he generally signed his articles) (1912–1978) was a distinguished Belgian specialist in Bantu languages, particularly those of the Belgian Congo, Rwanda and Burundi. Together with the British scholar Malcolm Guthrie (1903–1972) he is regarded as one of the two leading experts in Bantu languages in the second half of the 20th century. Meeussen was born at Sint-Pieters-Jette, Belgium on April 6, 1912, and died at Louvain on February 8, 1978, at the age of 65.
