Romero Rock (63°19′S 57°57′W) is a rock lying 0.1 nautical miles (0.2 km) west of Saavedra Rock in the Duroch Islands, Trinity Peninsula. The Chilean Antarctic Expedition of 1947-48, under the command of Navy Captain Ernesto Gonzalez Navarrete, made a survey of this area and gave the name "Islote Astronomo Romero" after Astronomer of the Chilean Army Guillermo Romero Gonzalez who was a member of the expedition and did astronomical work in the Antarctic. Around 1951 the name "Islote Romero" began to be used to avoid the compound name. The present name, Romero Rock, has been in use since 1962.
