Richard de Soham (died after 1305) was an English-born Crown official and judge who held high office in Ireland in the reign of King Edward I of England.
He is first heard of as a Crown official in 1286, as a tax collector in Yorkshire, charged with levying "the tenth": he was assistant to William de Beverley, a future Lord Chancellor of Ireland.
After a brief return home in 1294, he came back to Ireland as a Baron of the recently founded Court of Exchequer in 1295.
He was only the second judge appointed to the Court, joining Sir David de Offington (died 1312), another English-born official who had long been resident in Ireland.
He was appointed parish priest of Waddington, Lincolnshire in 1303, and presumably spent his last years there.
