Guercœur is an opera in three acts by the French composer Albéric Magnard to his own libretto. It was first performed posthumously at the Paris Opéra on 24 April 1931, though it had mostly been written between 1897 and 1901. The music shows the influence of Wagner.

History Albéric Magnard, a composer whose chamber and symphonic works were performed, composed Guercœur as his second opera to his own libretto between 1897 and 1901. He then tried in vain to find a theatre ready to produce it. The composer died trying to save his house from the invading Germans at the beginning of World War I in 1914, and the score was partially destroyed in the resulting fire. Magnard's friend Guy Ropartz reconstructed the missing sections from the vocal score so the opera could be staged.

It was first performed posthumously at the Paris Opéra on 24 April 1931.

Synopsis Guercœur, the wise ruler of a medieval city-state, has died in battle defending his people. In Heaven, he begs to be allowed to return to earth to save his city. His wish is granted but he finds his best friend, Heurtal, has become the lover of his widow, Giselle, and is planning to rule as a despot after marrying her. Shocked, Guercœur attempts to convince the people to reject corruption, but they become increasingly angry with him, and in the end he is murdered. Disillusioned with humanity, he returns to heaven, where he is greeted by the Goddess of Truth. She assures him that despite human weaknesses, a great age of humanity lies ahead.
