William Heyberer (died 1390/1), of Gloucester, was an English politician.
Heyberer's family had been prominent in Gloucester since the early fourteenth century. [1] In 1361 he became bailiff of the town and the same year represented Gloucester the House of Commons. [2] He was presumably one of the small group of influential merchants, who dominated Gloucester's trade in this period. [1] His first term as bailiff lasted until 1365, and he also served in the role in 1370-1, 1372-3, 1376-7 and 1384-5. [2] He represented Gloucester in parliament in 1362, 1365, 1371, 1372, 1373, October 1377, January 1380 and January 1390. [2] [3]
He rose to be a member of the local gentleman and sat as the Knight of the shire for Gloucestershire in November 1380, April 1384, November 1384, 1385 and February 1388. [2]
