NGC 5722 is a large lenticular galaxy in the constellation of Boötes. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . Additionally, one non-redshift measurement gives a slightly farther distance of . It was discovered by British astronomer John Herschel on 26 April 1830.
NGC 5722 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.
Compact galaxy group NGC 5722 is a member of a compact galaxy group catalogued as MLCG 1495. The other galaxies in the group are NGC 5721, NGC 5723, and SDSS J143853.22+464152.1.
