Mount Twintop () is a twin-peaked mountain about 6 nautical miles (11 km) south-southwest of Mount Tritoppen in the south part of the David Range, Framnes Mountains. Mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition (1936–37) and named Tvitoppen (the twin peak). The translated form of the name recommended by Antarctic Names Committee of Australia (ANCA) has been adopted.
