NGC 4650 is a large barred spiral galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . Additionally, one non-redshift measurement gives a closer distance of . It was discovered by British astronomer John Herschel on 26 June 1834.
NGC 4650 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.
