Nilsen Plateau () is a rugged, ice-covered plateau in Antarctica. When including Fram Mesa, the plateau is about 30 nautical miles (60 km) long and 1 to 12 nautical miles (22 km) wide, rising to 3,940 m between the upper reaches of the Amundsen and Scott Glaciers, in the Queen Maud Mountains. Discovered in November 1911 by the Norwegian expedition under Roald Amundsen, and named by him for Captain Thorvald Nilsen, commander of the ship Fram. The highest peak in Nilsen Plateau () is unnamed and has an elevation of 3940 metres.
