Lucienne Bréval (4 November 1869 in Zürich – 15 August 1935 in Neuilly-sur-Seine ) was a Swiss dramatic soprano who had a major international opera career from 1892-1918. Although she appeared throughout Europe and in the United States, Bréval spent most of her career performing with the Paris Opera where she became a greatly admired interpreter of French grand opera roles and Wagner heroines. She also specialized in the works of Gluck and Rameau, becoming particularly associated with the title roles in Gluck ’s Armide and Rameau's Hippolyte et Aricie . A favorite of the composers of her day, such as Massenet and Dukas, Bréval sang in numerous world premières during her career.

Jean-Baptiste Sebastien Bréval (6 November 1753 – 18 March 1823) was a French cellist and composer. He wrote mostly pieces for his own instrument, and performed many world premières of his own pieces.

John Durant Breval (1680?–January 1738) was a miscellaneous writer.
