NGC 1893 is an open cluster in the constellation Auriga. It is about 12,400 light years away. The star cluster is embedded in the Tadpole Nebula (HII region IC 410).[5]

Images of the star cluster by the Chandra X-ray Observatory suggest that it contains approximately 4,600 young stellar objects.[6]
