Anders Björner (born 17 December 1947)^[1] is a Swedish professor of mathematics, in the Department of Mathematics at the Royal Institute of Technology, Stockholm, Sweden. He received his Ph.D. from Stockholm University in 1979, under Bernt Lindström. His research interests are in combinatorics, as well as the related areas of algebra, geometry, topology, and computer science.^[2]

His other positions included being director of the Mittag-Leffler Institute^[3] and editor-in-chief of Acta Mathematica.^[4]

Björner is a recognized expert in algebraic and topological combinatorics.^[5] He is a 1983 recipient of the Pólya Prize, and is a member of the Royal Swedish Academy of Sciences since 1999.
