Todorova Island (Bulgarian: остров Тодорова, romanized: ostrov Todorova, IPA: [ˈɔstrof todoˈrɔvɐ]) is the triangular ice-covered island extending 1 km in southwest–northeast direction and 450 m in southeast–northwest direction, separated from the southwest coast of Belding Island in Biscoe Islands by a 1.2 km long passage narrowing to 80 m at points. Its surface area is 26.2 ha. The feature was formed as a result of the retreat of Belding Island's ice cap in 2011–2012.

The island is named after Katya Todorova, Deputy Foreign Minister responsible for Antarctica and member of the Antarctic Place-names Commission (2001–2005), participant in the Bulgarian Antarctic Expedition during the 2002/03 season.

Todorova Island is located at 66°24′13″S 67°15′54″W / 66.40361°S 67.26500°W / -66.40361; -67.26500, which is 4.2 km southwest of Yaglou Point and 3 km northeast of Decazes Island.
