IC 10 X-1 is an X-ray source located in the dwarf galaxy IC 10, an irregular galaxy. It corresponds to a high-mass X-ray binary in which the normal star is a Wolf–Rayet star and the compact object is a stellar black hole. The mass of this black hole makes it one of the most massive objects of this class known to date. It is also the first detected Wolf–Rayet star–black hole system; a second system was discovered shortly afterwards (NGC 300 X-1).
