Theodora (HWV 68) is a dramatic oratorio in three acts by George Frideric Handel, set to an English libretto by Thomas Morell. The oratorio concerns the Christian martyr Theodora and her Christian-converted Roman lover, Didymus. It had its first performance at Covent Garden Theatre on 16 March 1750. Not popular with audiences in Handel's day, Theodora is now recognised as a masterpiece. It is usually given in concert, being an oratorio, but is sometimes staged.
