This list contains known black holes relatively near the Solar System (within the Milky Way galaxy) compared to other known black holes.

Most black holes are thought to be solitary and not in a binary (or more) system. However, it is nearly impossible to detect such a black hole except for measuring its gravitational distortions of the light from more distant objects. Black holes in binary systems, despite constituting a minority of all black holes, are much easier to detect.[1] Therefore, solitary black holes would only be detectable by gravitational lensing. As of February 2022, only one isolated black hole has been detected, around 5200 light-years away.[2]

For comparison, the nearest star to the Sun is about 4.24 light years away and the Milky Way galaxy is approximately 185000 light years in diameter.
