Barnard 92 (abbreviated to B92) is a dark nebula located in the Small Sagittarius Star Cloud. It was discovered by American astronomer Edward Emerson Barnard.

B92 was initially referred to as "the black hole,"{{Cite book |last=Barnard |first=Edward Emerson |title=A photographic atlas of selected regions of the Milky Way |publisher=Carnegie Institution of Washington |year=1927 |isbn=9780511761133}} given its appearance, after it was first catalogued in 1913.{{Cite web |title=More M24: Barnard 92 Dark Nebula |url=http://www.messier.seds.org/more/m024_b92.html |access-date=2023-08-26 |website=www.messier.seds.org}} It was later discovered to be a dark nebula, and the title is now misleading, as the name black hole is used in modern astrophysics to describe a region of spacetime in which gravity is too strong for light to escape.
