Leopold Vietoris (/vˈtɔːrɪs/ vee-TOR-iss, German: [ˈleːopɔlt viːˈtoːʁɪs], Austrian German: [ˈleːopɔld viːˈtoːrɪs]; 4 June 1891 – 9 April 2002) was an Austrian mathematician, World War I veteran and supercentenarian. He was born in Radkersburg and died in Innsbruck.

He was known for his contributions to topology—notably the Mayer–Vietoris sequence—and other fields of mathematics, his interest in mathematical history, and for being a keen alpinist.
