Richard FitzJohn (died 1297) was an English nobleman who fought in Wales and Gascony and served as a judge in Ireland.
He succeeded his elder brother John FitzJohn in 1275, and inherited substantial lands in England.
Richard took part during King Edward I of England's great campaign in 1277 against Llywelyn ap Gruffudd in Wales.
As Captain of Bourg in Gascony, the garrison was besieged by a French army under the command of Henry III de Sully.
The King regranted these lands to the Irish judge William le Deveneys two years after Sir Richard's death.
