Results of photoelectric UBVRI photometry of 78 stars and photographic PDS and CCD photometry for 437 stars are presented for Collinder 110, an old open cluster at low Galactic latitude. Proper motions obtained from Lick Sky Survey plates were used to identify 39 stars as foreground objects. The cluster's reddening, distance, and age are estimated as E(B - V) = 0.50 ± 0.03 mag, r = 1950 ± 300 pc, and t = 1.4 ± 0.3 Gyr, assuming a solar metal abundance.
