61 Ursae Majoris is an orange-yellow main sequence dwarf star in the constellation Ursa Major. This star is somewhat smaller and fainter than the Sun, and can just barely be seen by the unaided eye (based on a magnitude limit of 6).

No sub-stellar companions have been observed in orbit around this star, and it appears to lack a dust ring as is found around some comparable stars. It lies near the same line of sight as the sub-giant star HD 101212, although it is presently unclear whether these two stars are gravitationally bound or even in physical proximity.

In fiction

* In the science fiction of Larry Niven, 61 Ursae Majoris is depicted as the home system of the warlike extraterrestrials known as Kzin.
* In the Star Trek science fiction universe, 61 Ursae Majoris is orbited by the class M planet Archer IV.
