McFarlane Strait is a strait lying between Greenwich Island and Livingston Island, in the South Shetland Islands off Antarctica. It is 24 kilometres (13 nmi) long and 3 kilometres (1.6 nmi) wide. The name appears on an 1822 chart by Captain George Powell, a British sealer, and is now well established in international usage.^[1]

The strait is centred at (62°32′S 59°55′W / 62.533°S 59.917°W / -62.533; -59.917), and entered between Williams Point and Duff Point to the northwest and between Renier Point and Ephraim Bluff to the southeast^[2] (British mapping in 1822 and 1968, Chilean mapping in 1971, Argentine mapping in 1980, Spanish mapping in 1991, and Bulgarian mapping in 2005 and 2009).
