Messier 60 (ka M60 ja NGC 4649) on elliptiline galaktika, mis asub Neitsi tähtkujus.

Messier 60 ja selle lähedal asuva Messier 59 avastas aprillis 1779 Johann Gottfried Koehler, kui ta vaatles komeeti. Prantsuse astronoom Charles Messier lisas mõlemad oma kataloogi umbes kolm päeva pärast Koehleri avastusi.[1]

Messier 60 on Neitsi galaktikaparve heleduselt kolmas galaktika. Galaktika keskel asub ülimassiivne must auk, mille mass on 4,5 ± 1 miljardit Päikese massi ja see on üks suurimaid teadaolevaid musti auke.[1] See asub Maast umbes 54 miljoni valgusaasta kaugusel ja selle diameeter on 120 000 valgusaastat.[2] Messier 60 tähesuurus on 9,8 ja see sisaldab 400 miljardit tähte.
