Larsen Nunatak () is a nunatak 2 nautical miles (3.7 km) north of Murdoch Nunatak in the Seal Nunataks group, off the east coast of Antarctic Peninsula. The Seal Nunataks were discovered by a Norwegian whaling expedition under C.A. Larsen in December 1893. Commemoration of Larsen was proposed by Ludwig Friederichsen in 1895. The application of this name is based upon a 1947 survey by the Falkland Islands Dependencies Survey (FIDS).
