815 Coppelia is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on 2 February 1916 from Heidelberg.[3]

Photometric observations of this asteroid at the Rozhen Observatory in Bulgaria during 2010 gave a light curve with a period of 4.4565 hours and a brightness variation of 0.24 in magnitude. This is consistent with a period of 4.421 hours and an amplitude of 0.27 obtained during a 2006 study.[2]
