Christmas Cliffs (73°33′S 94°17′W) are south-facing cliffs with two prominent rock outcrops, located 2 nautical miles (4 km) south-southeast of Pillsbury Tower in the Jones Mountains. They were mapped by the University of Minnesota Jones Mountains Party, 1960–61, and so named by the party because the cliffs were visited on Christmas Day, December 25, 1960.
