S Andromedae (also SN 1885A) was a supernova in the Andromeda Galaxy, the only one seen in that galaxy so far by astronomers, and the first ever noted outside the Milky Way.

The star was reported to be reddish in color and declined very rapidly in brightness, which is atypical for Type Ia supernovas. Unfortunately no spectroscopic data is available.

In 1988, astronomer R. A. Fesen and others, using the 4-meter Mayall telescope at Kitt Peak, discovered the iron-rich remnant of the explosion.
