Mathieu Moulart (1536–1600), alternatively Moullart or Moulard, was an abbot and bishop in the Habsburg Netherlands.
He was closely involved in Christopher Plantin's plan to print portable breviaries for Catholic clergy.
[1] As a representative of the clergy in the States of Hainaut, he was deputized to petition the Duke of Alva to modify his plans for unconstitutional innovations, and in 1572 he travelled to Rome and to Madrid to inform Pope Pius V and Philip II of Spain of events in the Low Countries, being absent from his monastery from 22 February to 2 November.
Reluctant to leave his monastery, he was not enthroned as bishop until 1 October 1577, and was not able to reside in his see until 1578, due to the opposition of the supporters of William the Silent.
He had a reputation for generosity to the sick, prisoners, widows and orphans, and to clerical refugees from the Dutch Revolt, but as a fierce opponent of heresy and superstition.
