NGC 5406 is a barred spiral galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 5,571±13 km/s, which corresponds to a Hubble distance of 268.0 ± 18.8 Mly (82.17 ± 5.76 Mpc). However, seven non-redshift measurements give a much closer mean distance of 140.06 ± 34.21 Mly (42.943 ± 10.489 Mpc). It was discovered by German-British astronomer William Herschel on 16 May 1787.

NGC 5406 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.

According to Abraham Mahtessian, NGC 5406 and NGC 5407 [fr] form a pair of galaxies.
