"Oberon" is an 1826 opera by German composer Carl Maria von Weber, who is known as the creator of German Romantic Opera, established by his most popular work "Der Freischütz" in 1821. Born November 18, 1786, von Weber had a somewhat successful career in music, though his personal life suffered many illnesses and setbacks, which affected his compositions and reputation in the music world. Von Weber was commissioned by the Opera at Covent Garden in London to compose an opera focused on either the fictional characters Faust or Oberon. Von Weber chose Oberon, the fairy king of Shakespeare's "A Midsummer Night's Dream" and accepted the commission, mostly for financial reasons and against the advice of his doctor. "Oberon" was von Weber's last work, written and staged in London in April 1826. The production took its toll on von Weber's already fragile health, leading to his death at 39 years of age on June 4th of the same year.

"Oberon" was written in English, though it has been successfully translated to von Weber's native German and is performed in both languages. Focusing on characters made famous by Shakespeare's "A Midsummer Night's Dream" including the titular Oberon, the fairy queen Titania, and Puck, the opera focuses on another instance of the fairies meddling with mortal lovers and their lives, this time in an orientalist, medieval setting. The libretto, written by James Robinson Planché, is an adaptation of the German poem "Oberon" by Christoph Martin Wieland, which is itself an adaptation of "Huon de Bordeaux", a 13th French epic poem. The opera is most known for its overture, and is still performed today.
