NGC 4611 is a intermediate spiral galaxy in the constellation of Coma Berenices. Its velocity with respect to the cosmic microwave background is 6,437 ± 22{{nbsp}}km/s, which corresponds to a Hubble distance of 94.9 ± 6.7{{nbsp}}Mpc (~310{{nbsp}}million light-years). It was discovered by French astronomer Édouard Stephan on 17 May 1881.{{cite web | url = https://cseligman.com/text/atlas/ngc46.htm#4611 | title = New General Catalogue Objects: NGC{{nbsp}}4611 | last = Seligman | first = Courtney | website = Celestial Atlas | access-date = 13 December 2024}} This galaxy was also observed by the American astronomer Lewis Swift on 20 April 1889, and listed in the Index Catalogue as IC 805.
