South Beaches are the beaches extending along the south side of Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica between Devils Point to the west and Rish Point to the east. The beaches were visited by 19th century sealers.
The feature was descriptively named, with the name 'South Beach' appearing on early mapping by Captain Robert Fildes and Captain George Powell in 1821 and 1822 respectively.
