Einar Hille (birth name Carl Einar Hille) was an American mathematician, born 28 June 1894 in New York, USA, and died 12 February 1980 in La Jolla, California.

Hille's main work was on integral equations, differential equations, special functions, Dirichlet series and Fourier series. Later in his career his interests turned more towards functional analysis.

His name persists among others in the Hille-Yosida theorem.

Hille was married to Kirsti Hille, daughter of mathematician Øystein Ore, and had two sons, Harald and Bertil Hille.
