611 Valeria is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on September 24, 1906, from Taunton, Massachusetts.[3] The reason that the name Valeria was chosen is unknown.[4]

Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico, during 2012 gave a light curve with a period of 6.977 ± 0.001 hours and a brightness variation of 0.08 ± 0.01 in magnitude. This result is consistent with a previous study from 2008.[2]
