15 Andromedae is a star in the constellation Andromeda. Its apparent magnitude is 5.55. Its estimated distance from the Earth is 233.47 light years.

This system has an excess emission of infrared radiation that suggests the presence of an orbiting disk of dust at a distance of around 50 AU from the host star.^[2]
