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.
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 / 62.660389°S 60.36750°W / -62.660389; -60.36750 which is 1.9 km south-southeast of Hespérides Point.
