Sh 2-5 is an emission nebula in the constellation Scorpius. It is part of the Sharpless Catalog assembled by Stewart Sharpless. [3] It is contained within the much larger War and Peace Nebula, listed in the Sharpless catalog as Sh 2-11, [4] and Sh 2-5 itself contains NGC 6337.

Like the nearby Sh 2-4, Sh 2-5 is probably ionized by the nearby star cluster Havlen-Moffat 1. However, it is also possible that ionization may be caused by nearer stars in the Sagittarius Arm. [5]
