Jean-Baptiste Stuck (also known by the single moniker "Baptistin," "Batistin" or "Battistin") (6 May 1680 – 8 December 1755) was an Italian-French composer and cellist of the Baroque era.

Little is known of Stuck's early years. He was born at Livorno on the coast of Tuscany, came from a merchant family, and was the son of Giovanni-Giacomo Stuck and Barbera Hellerbeck. From 1702 he was in the service of Countess Lemos in Naples. Stuck wrote arias for the performance of the opera L'innocente inganno of Tomaso Albinoni, which was performed under the new title Rodrigo in Algieri on 10 December 1702 in Naples at the Teatro San Bartolimeo.

Shortly thereafter Stuck moved to Paris. In 1705, he published the collection Für das Jahr 1701 through the Ballard publishing house. In Paris, he was a member of the Chapelle royale and a cellist in the service of Philippe II, Duke of Orléans. In 1722, he led the cello in the opera orchestra, displacing the bass viol. In 1733 he was naturalized French. He died in Paris.
