Raymond Smith Dugan (May 30 1878August 31 1940) was an American astronomer and a graduate of Amherst College in Massachusetts (1899).

He did his Masters Degree at Amherst College in 1902, and then did his Ph.D. dissertation in 1905 at the Landessternwarte Heidelberg-Königstuhl (Königstuhl Observatory, near Heidelberg) at the University of Heidelberg.

At the time, the observatory at Heidelberg was a center of asteroid discovery under Max Wolf. During Dugan's time there, he discovered 16 asteroids, including notably 511 Davida.

He was at Princeton University as an instructor (1905–1908), assistant professor (1908–1920), and professor (1920—). He married Annette Rumford in 1909.

He co-wrote an influential two-volume textbook in 1927 with Henry Norris Russell 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.

The asteroid 2772 Dugan was named in his honour.
