The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky. It is 1,344 ± 20 light-years away and is the closest region of massive star formation to Earth.

Half of degree north of the Orion Nebula lies the reflection nebulae NGC 1973, NGC 1975 and NGC 1977, also called the Running Man Nebula.
