Sharpless 101 (Sh2-101) is a H II region emission nebula located in the constellation Cygnus. It was catalogued by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years from Earth.
Sh2-101, at least in the field seen from earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes.
