John de Pilmuir [Pilmor, Pylmore] (died 1362) was a 14th-century prelate based in Scotland.
Originally a canon of the diocese of Ross, on 30 March 1326, he was consecrated by Pope John XXII as Bishop of Moray at Avignon.
The diocese of Moray had been reserved during the episcopate of David de Moravia, and this along with the lack of any record of an election in Moray makes it probable that Pilmuir was a direct appointment of the papacy.
He had previously been the vicar in spirituals of Pierre Roger, Archbishop of Rouen, the future Pope Clement VI.
He completed the foundation of the Scots College in Paris, initiated by his predecessor in Moray David de Moravia.
