Pompeo Sarnelli (born 28 January 1649, died 7 July 1724) was a Roman Catholic prelate who served as Bishop of Bisceglie (1692–1724).

There, he studied theology and law and, after he became a priest in 1669, worked for Cardinal Vincenzo Maria Orsini.

On 24 March 1692, he was appointed during the papacy of Pope Innocent XII as Bishop of Bisceglie.

[2][1] Throughout all his years of activity, Sarnelli wrote several erudite works, in prose and verse, including many elegies and odes in Latin, a commentary on Latin poems (Il filo d’Arianna) and Memories of the Bishops of Bisceglie and of the same Town (Naples 1693), in which church history and local history are fully mixed in a Counter-Reformation way.

For Bulifon's press, Sarnelli wrote theological and devotional treatises, school readers, and a collection of five fairy tales written in Neapolitan language which bore the title of Posilecheata (1684).
