Serpent Nunatak (69°28′S 70°55′W) is a nunatak which is seen in the shape of a reverse letter S, rising to about 750 m just west of Tufts Pass lying within the Nichols Snowfield, in the northern portion of Alexander Island, Antarctica. Descriptively named by United Kingdom Antarctic Place-Names Committee in 1977 because of the nunataks shape, the reverse letter S supposedly resembles a Serpent.
