Stanisław Mieczysław Mazur (1 January 1905, Lwów – 5 November 1981, Warsaw) was a Polish mathematician and a member of the Polish Academy of Sciences.

Mazur made important contributions to geometrical methods in linear and nonlinear functional analysis and to the study of Banach algebras. He was also interested in summability theory, infinite games and computable functions.

Mazur awards a live goose to Per Enflo, who solved Mazur's 1936 problem in the Scottish book. The photograph comes from the book Pół wieku matematyki polskiej 1920-1970 ("Half a Century of Polish Mathematics 1920-1970").

Mazur was a student of Stefan Banach at University of Lwów. His doctorate, under Banach's supervision, was awarded in 1935. Mazur, with Juliusz Schauder, was an Invited Speaker of the ICM in 1936 in Oslo.

Mazur was a close collaborator with Banach at Lwów and was a member of the Lwów School of Mathematics, where he participated in the mathematical activities at the Scottish Café. On 6 November 1936, he posed the "basis problem" of determining whether every Banach space has a Schauder basis, with Mazur promising a "live goose" as a reward: 37 years later and in a ceremony that was broadcast throughout Poland, Mazur awarded a live goose to Per Enflo for constructing a counter-example.

From 1948 Mazur worked at the University of Warsaw.
