Willan Saddle (Sedlovina Willan \\se-dlo-vi-'na 'wi-l&n\\) is a flat, crescent-shaped and ice-covered saddle extending 1 km in the northeast-southwest direction between Burdick South Peak and Willan Nunatak in eastern Livingston Island in the South Shetland Islands, Antarctica. The saddle has an elevation of 400 m and is part of the overland route between Balkan Snowfield and Charrúa Gap in the west and Orpheus Gate in the east, thus providing access from the Bulgarian Base and the Spanish Base to the interior of eastern Livingston Island. The feature takes its name from the adjacent Willan Nunatak.
