Richard FitzAlan, 10th Earl of Arundel (c. 1307 – January 24, 1376) was an English nobleman and military leader.

Despite his high offices in Wales, in the following decades Arundel spent much of his time fighting in Scotland (during the Second Wars of Scottish Independence) and France (during the Hundred Years' War). In 1337, Arundel was made joint commander of the English army in the north, and the next year he was made the sole commander.

In 1340 he fought at the Battle of Sluys, and then at the siege of Tournai. After a short term as warden of the Scottish Marches, he returned to the continent, where he fought in a number of campaigns, and was appointed Joint Lieutanant of Aquitaine in 1340.

Arundel was one of the three principal English commanders at the Battle of Crécy. He spent much of the following years on various military campaigns and diplomatic missions.
