Magnus Gustaf (Gösta) Mittag-Leffler (16 March 1846 – 7 July 1927) was a Swedish mathematician. His mathematical contributions are connected chiefly with the theory of functions.
Mittag-Leffler was born in , son of the school principal John Olof Leffler and Gustava Wilhelmina Mittag; he later added his mother's maiden name to his paternal surname. His sister was the writer Anne Charlotte Leffler. He matriculated at Uppsala University in 1865, completed his Ph.D. in 1872 and became docent at the university the same year. He was also curator (chairman) of the (1872–1873). He next traveled to Paris, Göttingen and Berlin, studying under Weierstrass in the latter place. He then took up a position as professor of mathematics (as successor to Lorenz Lindelöf) at the University of Helsinki from 1877 to 1881 and then as the first professor of mathematics at the (the later ); he was president of the college from 1891 to 1892 and retired from his chair in 1911.
