Rolin-Louis Wavre (25 March 1896 in Neuchâtel – 9 December 1949 in Geneva) was a Swiss mathematician. Wavre studied at the Sorbonne and received his Ph.D. in 1921 from the University of Geneva, where he became a professor extraordinarius in 1922, and a professor ordinarius in 1934 (as successor to Charles Cailler). Wavre did research on, among other subjects, logic and the philosophy of mathematics, in which he was an adherent of Brouwer's intuitionism. Independently of, and almost simultaneously with, Leon Lichtenstein, he dealt with equilibrium figures of a heterogeneous fluid mass, with a view to applications to planetary systems in astrophysics.
