Sh2 -112 is a faint emission nebula in the constellation Cygnus.

It is located in the northern part of the constellation, about 1.5° west of the bright star Deneb (One of the stars of the so-called Summer Triangle). It is a circular H II region with an apparent size of about 15′, crossed by a dark band on the west side oriented north-south. Estimates of the distance to this nebula give a value of about 5670 light-years, which would place Sh2-112 in a particularly rich region of the Orion arm and physically very close to the large nebular system of Cygnus X.
