NGC 3449 is a spiral galaxy in the constellation of Antlia. Its velocity with respect to the cosmic microwave background is 3,609±17 km/s, which corresponds to a Hubble distance of 173.6 ± 12.2 Mly (53.23 ± 3.74 Mpc). However, 20 non-redshift measurements give a closer mean distance of 151.97 ± 3.98 Mly (46.595 ± 1.221 Mpc). It was discovered by British astronomer John Herschel on 29 April 1834.
