Die Hochzeit (The Wedding) (WWV 31) is an unfinished opera by Richard Wagner which predates his completed works in the genre. Wagner completed the libretto, then started composing the music in the second half of 1832 when he was just nineteen. He abandoned the project after his sister Rosalie, who was the main supporter and the spokesman of the family, expressed her disgust at the story. Wagner destroyed the libretto.

Today, only three pieces survive from the opera.

What is still known of the story is that it concerns the events surrounding the intended marriage of a young woman, Ada, to Arindal. This is a political marriage, not one of love. On the eve of the wedding, Ada's lover, Cadolt, comes to see her. She rejects his advances, preferring to defend her honour but, in the process, pushes him over the balcony to his death. Ada still loves Cadolt and collapses and dies at the funeral next to his body.
