Boris Yakovlovic Bukreev (September 6, 1859 - October 2, 1962) was a Russian mathematician who worked in the areas of complex functions and differential equations.
In 1889, Bukreev became a professor of mathematics at the University of Kiev, in the Ukraine. He studied Fuchsian functions of rank zero. He was interested in projective and non-Euclidean geometry. He worked on differential invariants and parameters in the theory of surfaces. The history of mathematics interested him.
