NGC 4727 is a large barred spiral galaxy in the constellation of Corvus. Its velocity with respect to the cosmic microwave background for is 7,830±23 km/s, which corresponds to a Hubble distance of 376.7 ± 26.4 Mly (115.49 ± 8.09 Mpc).[1] It was discovered by German-British astronomer William Herschel on 8 February 1785.[2] It was also observed by Lewis Swift on 27 April 1887, causing it to be listed twice in the New General Catalogue, as NGC 4727 and as NGC 4740.[2]

NGC 4727 and NGC 4724 [fr] are listed together as Holm 470 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.[3]
