Open Cluster NGC 2175 (also known as OCL 476 or Cr 84) is an open cluster in the Orion constellation, embedded in a diffusion nebula.

NGC 2175 is at a distance of about 6,350 light years away from Earth.

The nebula surrounding it is Sharpless catalog Sh 2-252, and it is sometimes called the Monkey Head Nebula due to its appearance.

These may apply to the entire nebula, to its brightest knot, or to the star cluster it includes.

Burnham's Celestial Handbook lists the entire nebula as 2174/2175 and does not mention the star cluster.
