Longstaff Peaks () is a series of high peaks standing just west of Davidson Glacier in the N-central part of the Holland Range. Discovered by the Discovery expedition (1901–04), and named Mount Longstaff for Llewellyn W. Longstaff, principal contributor to the expedition. The descriptive term was amended by the New Zealand Antarctic Place-Names Committee (NZ-APC).
