Perley Ason Ross (6 April, 1883 - 13 March, 1939) was a U.S. experimental physicist who worked, carefully and without seeking publicity, at some essential problems in the behaviour of X-rays. cite web | author=Webster, D.

Born Panacea, Missouri he was awarded his PhD from Stanford University in 1911, becoming a full professor there in 1927, after a year at Cornell University.

Some of his principal studies included:
*Scattering of X-rays by matter;
*Development of the Ross differential filter for X-ray spectroscopy;
*X-ray polarization; and
*Compton scattering. [cite journal | journal=Proceedings of the National Academy of Sciences | author=Ross, P. A. | title=PDF| [http://www.pnas.org/cgi/reprint/9/7/246.pdf Change in wave-length by scattering] | year=1923 | volume=9 | pages=246–248 ()]

His daughter, Betsy, married fellow Stanford physicist William Webster Hansen. [Süsskind, C. (1981) "Hansen, William Webster" in cite book | author=Gillespie, C.C.
