Theodora Komnene (Greek: Θεοδώρα ἡ Κομνηνή, born circa 1134, died 2 January 1184), Latinized Theodora Comnena, was a daughter of the Byzantine prince Andronikos Komnenos and his wife, Eirene (?Aineiadissa).

Based on the writings of Niketas Choniates, it is likely Theodora was Andronikos' second daughter.

She does not appear in the historical record again until the late 1140s, when she was betrothed to and married Henry II of Austria, whose first wife, Gertrude of Supplingenburg had died in 1143.

[1] The marriage had been arranged by her uncle, Manuel I and her eventual husband's half-brother, Conrad III of Germany, during the latter's stay in Constantinople.

[2] Theodora and Henry were married in Constantinople, and subsequently granted the Duchy of Austria by Frederick I Barbarossa in 1156.
