2063 Bacchus (/ˈbækəs/ BAK-əs) is an Apollo asteroid and Venus- and Mars-crosser asteroid. It was discovered on April 24, 1977, by Charles T. Kowal at the Palomar Observatory. In March 1996 radar observations were conducted at the Goldstone Observatory under the direction of JPL scientists Steven Ostro and Lance Benner, allowing the construction of a model of the object.[2] Optical observations were conducted by Petr Pravec, Marek Wolf, and Lenka Šarounová during March and April 1996.

Bacchus is about 2.6×1.1×1.1 km[1] in size and has a bilobate shape. Its spectral type is Sq.[1]

Its name derives from the Roman god Bacchus.
