Michel-Celse-Roger de Bussy-Rabutin

Michel-Celse-Roger de Bussy-Rabutin (1669 – 3 November 1736) was a French churchman and diplomat.

The second son of Count Roger de Bussy-Rabutin, he served as Bishop of Luçon from 1723 until his death.

He attended the salon of Madame de Tencin; he was elected to the Académie française on 21 February 1732, without having written a single work, being sponsored into the French Academy by Fontenelle the following 6 March.

In 1735 he commissioned a portrait of himself by Hyacinthe Rigaud without knowing how he would pay for it – the artist's accounting books state "Monsieur the Bishop of Luçon, Bussy-Rabutin.
