The Grand Chasms (78°35′S 39°30′W / 78.583°S 39.500°W / -78.583; -39.500) are two or more deep crevasses in the Filchner Ice Shelf, Antarctica, extending west for an unknown distance from 37°W, close west of the Touchdown Hills.
The feature is the most notable crevassed area on the Filchner Ice Shelf, roughly 60 miles (100 km) long and from 0.25 to 3 miles (0.4 to 4.8 km) wide.
During 1957 it was examined by a U.S. party from Ellsworth Station led by Edward Thiel, who applied the descriptive name.
