Mu Lupi (μ Lup) is a system of three or four[7] stars in the southern constellation of Lupus. It is visible to the naked eye with an apparent visual magnitude of 4.29[2] and lies roughly 340 light-years from the Sun.

Two of the components of this system, A and B, form a pair with an angular separation of 1.1 arcseconds. As of 2014, no orbit has been published. Component C lies at an angular separation of 22.6 arcseconds from the AB pair, and may be a common proper motion companion. It is an A-type main-sequence star with a classification of A2 V. A fourth component at an angular separation of 6.15 arcseconds from component A, may be a brown dwarf.[7]
