Robert III de La Marck (1491–1537), Seigneur of Fleuranges, was a Marshal of France and historian. Self-styled "The Young Adventurer," he was one of Francis I's close companions in the last years of Louis XII's life, and remained close after Francis ascended the throne. Robert campaigned with Francis' Italian campaigns being captured at Pavia. During his imprisonment he wrote a personal history. Upon being freed, he returned to participation in the Italian Wars, seeing service at the defence of Péronne in 1536. When he learnt of his father's death, he set out for Amboise, but was stricken by illness and died at Longjumeau in 1537.
