Comet 177P/Barnard, also known as Barnard 2, is a periodic comet in the solar system.

The comet, also designated P/2006 M3, discovered by Edward Emerson Barnard on June 24, 1889, and was re-discovered after 116 years.[2] On July 19, 2006, 177P came within 0.36 AU of the Earth.[3] From late July through September of 2006 it was brighter than expected at 8th magnitude in the constellations Hercules and then Draco. Perihelion was August 28, 2006.

Of Barnard's other two periodic comets, the first, D/1884 O1 (Barnard 1) was last seen on November 20, 1884 and is thought to have disintegrated. The last, 206P/Barnard-Boattini marked the beginning of a new era in cometary astronomy, as it was the first to be discovered by photography. It was a lost comet after 1892, until accidentally rediscovered on October 7, 2008 by Andrea Boattini.
