Pusat Galaktik adalah pusat putaran galaksi Bima Sakti. Ia terletak pada jarak 8,33 ± 0,35 kpc (~ 27.000 ± 1.000 ly) dari Bumi[1][2][3][4][5] dalam arah buruj Sagittarius,Ophiuchus, dan Scorpius di mana Bima Sakti kelihatan paling terang. Terdapat bukti kukuh yang menyokong kewujudan lubang gergasi besar hitam di Pusat Galaktik Bima Sakti.
