Pierre Joseph Ferret (1908–1978) was a Gypsy jazz guitarist and composer. He was known by his Gypsy nickname "Baro," which meant "Big One" or even "King" in Romany. Through his brother Jean "Matelo" Ferret, Baro met Jean "Django" Reinhardt, and the two became both friends and notorious rivals. From 1931, the Ferret brothers, along with their third brother Etienne "Sarane" Ferret', and cousin René "Challain" Ferret, were favorite sidemen of Reinhardt.
