NGC 2342 is a spiral galaxy in the constellation of Gemini. Its velocity with respect to the cosmic microwave background is 5445 ± 11 km/s, which corresponds to a Hubble distance of 80.31 ± 5.62 Mpc (∼262 million light-years).[1] It was discovered by German astronomer Albert Marth on 10 November 1864.[2]

NGC 2342 is a luminous infrared galaxy (LIRG).[1] Together with NGC 2341, they both form a gravitationally bound galaxy pair listed as HOLM 86.[3]

One supernova has been observed in NGC 2342: SN 2023vck (type Ib, mag 19.917) was discovered by the Zwicky Transient Facility on 15 October 2023.[4]
