The [[Bayer designation]] '''Pi Ursae Majoris''' (π UMa, π Ursae Majoris) is shared by two [[star]]s in the [[constellation]] [[Ursa Major]]:

* [[Pi¹ Ursae Majoris]] (3 Ursae Majoris)
* [[Pi² Ursae Majoris]] (4 Ursae Majoris)

They are separated by 0.70° in the sky.  They are sometimes given the name '''Muscida''', which can also refer to [[Omicron Ursae Majoris|ο Ursae Majoris]].

The two stars, Pi¹ and Pi² together, are considered an optical [[double star]]. They are not a [[binary star]], in that they are not gravitationally linked, but they are close to each other as seen in the sky, and so are optically associated.
