NGC 1980 (also known as OCL 529) is a young open cluster associated with an emission nebula which is located in the constellation Orion. It was discovered by John Herschel on 31 November 1786. Its size is 14.00 by 14.0 arc minutes and is located around the star Iota Orionis on the southern tip of the Orion Constellation.

Even though Herschel made his first observation of the cluster which was called WH V 31 on 31 November 1786, but he possibly observed it during his studies of double stars on September 20, 1783.
