Helena Megale Komnene (Greek: Έλενα Μεγάλη Κομνηνή, romanized: Elena Megalē Komnēnē; Georgian: ელენა კომნენა) (died 1366) is the name given for the first wife of King Bagrat V of Georgia. Her first name is recorded in The Georgian Chronicles,^[1] and her family name is based on a theory which identifies her as a daughter of Basil of Trebizond.^{[citation needed]} If true, the identity of her mother would be uncertain. Basil was bigamous, concurrently married to Irene Palaiologina and Irene of Trebizond.

Helena died in 1366, victim to a plague which had spread across Georgia during the 1350s and 1360s (possibly a recurrence of the Black Death).^[2]

A year after her death, her husband married Anna of Trebizond.^[3]

According to the Georgian Chronicle, Helena was survived by two children:^{[citation needed]}

• George VII of Georgia
• David. Otherwise unknown.
