Johnsons Dock is a sheltered 500 m wide cove indenting for 900 m the northwest coast of Hurd Peninsula on Livingston Island in the South Shetland Islands, Antarctica. It is part of South Bay entered north of Ballester Point. Surmounted by Charrúa Ridge on the northeast. The cove was frequented by early 19th century sealers.
The feature is probably named after Captain Thomas Johnson, Master of the British brig Mellona or Captain Robert Johnson, Master of the American sealing ship Jane Maria and of the schooner Wasp, who visited the South Shetland Islands in the first seasons after their discovery.
The cove's midpoint is located at 62°39′37.4″S 60°22′03″W which is 1.9 km south-southeast of Hespérides Point. British early mapping in 1822 and 1968, detailed Spanish mapping in 1991, Bulgarian mapping in 1996, 2005 and 2009.
