The Allen Rocks (77°33′S169°9′E) are a small but distinctive group of rocks 2.2 nautical miles (4.1 km) east-northeast of Slattery Peak in the Kyle Hills, Ross Island. The feature includes a central nunatak that in outline resembles the letter 'A'. A low ridge encloses the nunatak except on the south. The group was named by the Advisory Committee on Antarctic Names in 2000 after Robert J. Allen of the U.S.
