NGC 3862 is an elliptical galaxy located 300 million light-years away[2] in the constellation Leo.[3] Discovered by astronomer William Herschel on April 27, 1785,[4] NGC 3862 is an outlying member of the Leo Cluster.[5]

The galaxy is classified as a FR I radio galaxy[6] and as a Head-tail radio galaxy.[7][8] It hosts a supermassive black hole that is blasting a jet of plasma that is moving at 98 percent of the speed of light and is one of the few jets that can be seen in visible light.[9]

One supernova has been observed in NGC 3862: SN 2023bqk (type Ia-pec, mag. 18.3).[10]
