Philippe Pierlot (born 1958) is a Belgian viola da gamba player and a conductor in historically informed performance.

Born in Liège, Pierlot learned to play the recorder, the guitar and the lute at the age of twelve.

In 1980, he founded the ensemble Ricercar Consort, with the violinist François Fernandez and the keyboard player Bernard Foccroulle, focusing on the performance and recording of little-known music in historically informed performance.

In 1999, he revived Marais's opera Sémélé, which had not been performed for 300 years, after composing some missing parts.

[1] Until 2006, Pierlot was professor for viola da gamba at the Hochschule für Musik Trossingen [de].
