NGC 300 X-1 is a high mass X-ray binary system located in the spiral galaxy NGC 300, approximately 6 million light-years away in the constellation of Sculptor. It consists of a stellar-mass black hole orbiting a Wolf–Rayet star (specifically of WN spectral type), making it one of only a few confirmed extragalactic Wolf–Rayet-black hole binary systems, the other prominent example being IC 10 X-1.
