Richard le Brun (died after 1324) was an English-born cleric, judge and Crown official in fourteenth-century Ireland.
Richard later moved to Ireland and obtained a position at the Exchequer, where he was described as a "King's clerk".
His precise job was "engrosser", which generally meant a copier of deeds, but in view of his later eminence, it was presumably a senior enough position.
In 1320 Nicholas Babau acknowledged that Richard and William de Bardelby, afterwards Master of the Rolls in Ireland, had the right to a crop of wheat in Balgoray (possibly Ballygorey, County Kilkenny).
The second Richard served as a justice of the Court of Common Pleas (Ireland) in the 1330s.
