Sir Nicholas Brembre (died 20 February 1388) was a wealthy magnate and a chief ally of King Richard II in 14th-century England. He was Lord Mayor of London in 1377, and again from 1384–5,6. Named a "worthie and puissant man of the city" by Richard Grafton (who wrongly termed him a draper), he became a citizen and grocer of London, and in 1372-3 purchased[1] from the Malmains family the estates of Mereworth, Maplescomb, and West Peckham, in Kent.[2] His ties to Richard ultimately resulted in his downfall, as the anti-Richard Lords Appellant effectively took control of the government and imprisoned, exiled, or executed most of Richard's court. Despite Richard's efforts, Brembre was executed in 1388 for treason at the behest of the Lords Appellant.
