NGC 7329 is a large barred spiral galaxy located in the constellation Tucana. Its velocity with respect to the cosmic microwave background is 3,148±8 km/s, which corresponds to a Hubble distance of 151.4 ± 10.6 Mly (46.43 ± 3.25 Mpc). Additionally, 29 non-redshift measurements give a closer mean distance of 145.67 ± 3.35 Mly (44.662 ± 1.028 Mpc). It was discovered by British astronomer John Herschel on 20 July 1835.

The luminosity class of NGC 7329 is II and it has a broad HI line.
