SW Andromedae is a variable star in the constellation of Andromeda. It is classified as an RR Lyrae star, and varies from an apparent magnitude of 10.09 at minimum brightness to a magnitude of 9.14 at maximum brightness with a period of 0.44226 days. It exhibits the Blazhko effect, and its period is decreasing.

The discovery of this star by Annie Jump Cannon was announced in 1907. 461 photographic plates, spanning the time interval from November 14, 1889 through November 16, 1906 were examined, and an initial period of 0.49932 days was derived. SW Andromedae was given its variable star designation in 1907.
