Pierre-Étienne Monnot (9 August 1657 – 24 August 1733) was a French sculptor from the Franche-Comté who settled in Rome in 1687 for the rest of his life.
He was a distinguished artist working in a late-Baroque idiom for international clients.
In Italian sources he is often referred to as Pietro Stefano Monnot, an italianised version of his name.
