Jasus paulensis, also commonly known as the St Paul rock lobster, is a species of spiny lobster found in the waters around Saint Paul Island in the southern Indian Ocean and around Tristan da Cunha in the southern Atlantic Ocean.

Like other rock lobsters, it lacks chelae (claws) on its front pair of walking legs.

[1] A previously recognised species Jasus tristani, found around Tristan da Cunha in the southern Atlantic Ocean, has now been synonymised with J.

[6] In 1928, a large-scale fishery and cannery for the spiny lobster using lobster pots was set up on St Paul, but the company went bankrupt three years later, stranding seven people on the island and leading to a tragedy known as "Les Oubliés de Saint-Paul" (the forgotten ones of Saint-Paul).

[8] Before 1950, the rock lobster on the Tristan da Cunha archipelago was only fished for local consumption.
