The Tinker Glacier (74°00′S 164°50′E / 74.000°S 164.833°E / -74.000; 164.833) is a 25 nautical miles (46 km; 29 mi) long glacier in Antarctica, draining the central part of the Southern Cross Mountains and flowing southeast into Wood Bay, on the coast of Victoria Land. Named by the Northern Party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1962–63, for Lieutenant Colonel Ron Tinker, leader at Scott Base during that season.

Tinker Glacier forms in the Southern Cross Mountains to the south of the Schulte Hills, and flows south past Mount Jiracek to the west, running parallel to Aviator Glacier to the east. Burns Glacier joins from the west. The Clausnitzer Glacier joins from the west before the Harrow Peaks. Tinker glacier forms the Tinker Glacier Tongue when it flows past Cape Johnson into Wood Bay of the Ross Sea.
