Henry Norris Russell (October 25, 1877 - February 18, 1957) was a US astronomer who, along with Ejnar Hertzsprung, developed the Hertzsprung-Russell diagram (1910).

Russell received the 1925 Bruce Medal.

Co-wrote an influential two-volume textbook in 1927 with Raymond Smith Dugan and John Quincy Stewart: Astronomy: A Revision of Young�s Manual of Astronomy (Ginn & Co., Boston, 1926-27, 1938, 1945). This became the standard astronomy textbook for about two decades. There were two volumes: the first was The Solar System and the second was Astrophysics and Stellar Astronomy.
