Turnpike Bluff (80°44′S 30°4′W / 80.733°S 30.067°W / -80.733; -30.067) is a conspicuous rock formation in the Shackleton Mountains of Antarctica.

[1] First mapped in 1957 by the Commonwealth Trans-Antarctic Expedition, and so named because it marks entry to a crevassed area of Recovery Glacier through which the Expedition's vehicles had difficulty in passing on their journey from Shackleton Base to the South Pole in 1957.

[1] Turnpike Bluff is in the south of the Otter Highlands, to the north of the Recovery Glacier.

[1] The Turnpike Bluff Group is a sedimentary sequence of rocks exposed on the south flank of the Shackleton Range.

[3] The group contains four formations, named after Wyeth Heights, Stephenson Bastion, Flett Crags and Mount Wegener.
