NGC 3437 is a barred spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 1,597±23 km/s, which corresponds to a Hubble distance of 76.8 ± 5.5 Mly (23.56 ± 1.68 Mpc). Additionally, 17 non-redshift measurements give a similar mean distance of 79.12 ± 2.14 Mly (24.259 ± 0.656 Mpc). It was discovered by German-British astronomer William Herschel on 12 March 1784.

NGC 3437 is listed as a radio galaxy.
