NGC 3277 is a spiral galaxy in the constellation of Leo Minor. Its velocity with respect to the cosmic microwave background is 1,712±21 km/s, which corresponds to a Hubble distance of 82.4 ± 5.9 Mly (25.26 ± 1.80 Mpc). However, five non-redshift measurements give a much farther mean distance of 148.34 ± 17.58 Mly (45.480 ± 5.389 Mpc). It was discovered by German-British astronomer William Herschel on 11 April 1785.

NGC 3277 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.
