NGC 3430 is a barred spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 1,869 ± 20 km/s, which corresponds to a Hubble distance of 27.6 ± 2.0 Mpc (∼90 million light-years). ^[1] It was discovered by German-British astronomer William Herschel on 7 December 1785.

Two supernovae have been observed in NGC 3936: SN 2004ez ( type II, mag. 17.3), ^[2] and PSN J10520833+3256394 (type IIb, mag. 17.8). ^[3]
