NGC 1893 is an open cluster in the constellation Auriga. It is about 3,280 light years away. The star cluster is embedded in the HII region IC 410,[5] an emission nebula shaped like a tadpole.

Images of the star cluster by the Chandra X-ray Observatory suggest that it contains approximately 4600 young stellar objects.[6]
