Fulk of Neuilly[1] (died 1201) was a French preacher of the twelfth century, and priest of Neuilly-sur-Marne. He preached the Fourth Crusade.
A priest at Neuilly from 1191, he attended the lectures of Peter the Chanter in Paris. He began to preach, and gained a reputation for piety and eloquence. An invitation for him to preach the Crusade came from Pope Innocent III in 1199. Both Simon de Montfort, 5th Earl of Leicester and Alix de Montmorency were influenced by him[2].
His assiduous enthusiasm in carrying out his mission led to rumours concerning the usage made of the monetary sums it produced. He died shortly afterwards.
