Quiroga Ridge (Bulgarian: хребет Кирога, 'Hrebet Quiroga' \'hre-bet ki-'ro-ga\) is a submarine ridge in False Bay, Livingston Island in the South Shetland Islands of Antarctica. It extends 2.2 km in an east-southeast to west-northwest direction between Ogosta Point on the Rozhen Peninsula and the opposite coast of Hurd Peninsula at a depth of over 50 m, with depths exceeding 100 m on both sides of the ridge. It was formed as a frontal moraine of Huntress Glacier between the 13th and 17th centuries.

The feature is named after Víctor Quiroga Martínez, captain of the Spanish ocean exploration ship BIO Hespérides that rendered logistic support to the Bulgarian Antarctic campaigns in the 1990s.

Quiroga Ridge is centred at 62°42′24″S 60°20′50″W / 62.70667°S 60.34722°W / -62.70667; -60.34722. Spanish mapping in 1991.
