Larvik Harbor (64°29′S 62°27′W) is a small bay southwest of Lagrange Peak in southeastern Brabant Island, Palmer Archipelago, Antarctica. The bay was roughly charted by a British expedition, 1920–22, and so named after the town of Larvik in southern Norway, following the name usage of whalers (M.C. Lester's amendments to Captain Johans Johannessen's manuscript chart of about 1919–20).^[1]
