Feast in Time of Plague is an opera (literally labeled "dramatic scenes") in one act by César Cui, composed in 1900. The libretto was taken verbatim from one of the four Little Tragedies by Aleksandr Pushkin. The title has been translated also as Feast in the Time of the Plague and Feast during the Plague.

Cui composed and published the two songs in the play (i.e., "Mary's Song" and "Walsingham's Hymn") separately in the decade before the opera was formally composed.

The opera was premiered on 11 November 1901 (Old Style), in Moscow at the Noviy Theater. Although it never became part of the standard repertory, Feast was revived by the Tchaikovsky Opera in Perm, Russia in 1999 as part of a Pushkin-bicentennial performance of all four of the operatic settings of the Little Tragedies, i.e., Dargomyzhsky's The Stone Guest, Rimsky-Korsakov's Mozart and Salieri, and Rachmaninoff's The Miserly Knight.

Feast was given its American premiere on October 14, 2009 by the Little Opera Theater of New York, directed by Philip Shneidman.

A CD recording of Feast was issued on the Chandos label in 2004, with the Russian State Symphony Orchestra under Valery Polyansky.
