Peake-Jones Rock is a low, bean-shaped rock lying just off the coast and 2nmi northeast of Ring Rock in Holme Bay, Mac. Robertson Land. The rock was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37. It was named by Antarctic Names Committee of Australia (ANCA) for K. Peake-Jones, weather observer at Mawson Station in 1959.
