Michel-Celse-Roger de Bussy-Rabutin (1669 – 3 November 1736) was a French churchman.
The second son of count Roger de Bussy-Rabutin, he was bishop of Luçon from 1723 until his death. He attended the salon of Madame de Tencin and was elected to the Académie française on 21 February 1732, without having written a single work, and was received into the Académie by Fontenelle the following 6 March. In 1735 he commissioned a portrait of himself from Hyacinthe Rigaud without knowing how he would pay for it - the artist's account books state "Monsieur the bishop of Lucon, Bussy Rabutin. Remains half finished."[1].
