Peter of Bourbon-La Marche (1342 – 1362 in Lyon) was the eldest son of James I, Count of La Marche[1] and Jeanne of Chatillon, and was a French prince du sang.
He was knighted by his father shortly before the Battle of Brignais, in which both father and son fought.[2] Both were mortally wounded during the battle,[2] but were carried away by their soldiers to Lyon. He survived his father only a short while, and was succeeded by his brother John.
