Das Pfauenfest is a singspiel in two acts by composer Johann Rudolf Zumsteeg.

The opera has a German libretto by F. A. C. Werthes and premiered at the court theatre in Stuttgart on 24 February 1801.

The fairy Morgana wickedly conspires against Lenore; spreading malicious lies about her.

As a result, Lenore loses the love of Karados, a knight, and is banished from King Arthur's court.

The two are scheduled to be betrothed at the Feast of the Peacock, and King Arthur orders that Lenore be brought back to court to witness the event.
