Ferguslie Peninsula is a peninsula 2.4 km (1.5 mi) long, lying between Browns Bay and Macdougal Bay on the north coast of Laurie Island, in the South Orkney Islands of Antarctica.

It was named by Bruce for Professor Patrick Geddes, a noted Scottish biologist and sociologist.

[3] A 99 ha tract of ice-free land, including Cape Geddes and the eastern side of the peninsula, has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a large breeding colony of about 12,000 pairs of chinstrap penguins.

Other birds nesting at the site include over 200 pairs of southern giant petrels at Cape Geddes.
