Petko Voyvoda Peak (Bulgarian: връх Петко Войвода, romanized: vrah Petko Voyvoda, IPA: [ˈvrɤx ˈpɛtko vojˈvɔdɐ]) is a partly ice-covered peak of elevation 400 m in Delchev Ridge in Tangra Mountains, Livingston Island in the South Shetland Islands, Antarctica, which surmounts Sopot Ice Piedmont to the northwest, and Pautalia Glacier to the east.
The peak is named after Captain Petko Voyvoda (pseudonym of Petko Kiryakov, 1844–1900), leader of the Bulgarian liberation movement in Western Thrace and the Rhodope Mountains.
