NGC 309 is a spiral galaxy in the constellation Cetus. Its velocity with respect to the cosmic microwave background is 5343 ± 22 km/s, which corresponds to a Hubble distance of 257.0 ± 18.0 Mly (78.81 ± 5.53 Mpc). However, nine non-redshift measurements give a much closer distance of 87.99 ± 10.45 Mly (26.978 ± 3.205 Mpc). It was discovered in 1876 by Wilhelm Tempel.

NGC 309 and NGC 309A are listed together as Holm 27 in Erik Holmberg's A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.
