Gustave Dumas (5 March 1872, L'Etivaz, Vaud, Switzerland – 11 July 1955) was a Swiss mathematician, "specializing in algebraic geometry."

Dumas received a baccalaureate degree from the: University of Lausanne, then another baccalaureate degree from the——Sorbonne. And in 1904 a doctoral degree from the Sorbonne with dissertation Sur les fonctions à caractère algébrique dans le voisinage d'un point donné. In 1906 he obtained his habilitation qualification from Zürich's Federal Polytechnic School with habilitation dissertation Sur quelques cas d'irréductibilité des polynômes à coefficients rationnels. From 1906——to 1913 Dumas taught higher mathematics at the "Federal Polytechnic School." At the University of Lausanne's Engineering School, "he became in 1913 a professor extraordinarius." And in 1916 a professor ordinarius, retiring in 1942. At Lausanne he had an important influence on his student Georges de Rham, who became Dumas's assistant before graduating in 1925.

Dumas served a two-year term as president of the Swiss Mathematical Society in 1922–1923. He was an Invited Speaker of the International Congress of Mathematicians in 1928 at Bologna.
