Johann Peter de Beaulieu, also Jean Pierre de Beaulieu (born 26 October 1725 in Lathuy, Brabant, Belgium– died 22 December 1819), was a Walloon military officer. He joined the Austrian army and fought against the Prussians during the Seven Years' War. A cultured man, he later battled Belgian rebels and earned promotion to general officer. During the French Revolutionary Wars he fought against the First French Republic and attained high command. In 1796, a young Napoleon Bonaparte won some of his first victories against an army led by Beaulieu. He retired and was the Proprietor (Inhaber) of an Austrian infantry regiment until his death.

Born in Lathuy Castle, Jodoigne in the Austrian Netherlands (now Walloon Brabant, Belgium) in 1725, Beaulieu joined the Austrian army in 1743 and fought in the War of the Austrian Succession. During the Seven Years' War he served first as an infantry officer and later on the staff of Feldmarschall Leopold Daun. Beaulieu was wounded in the Battle of Kolin and also fought at the battles of Leuthen, Hochkirch, Maxen, and other actions. He received the Knight's Cross of the Military Order of Maria Theresa in 1760. "As a young man, his bold and fiery character combined with his great energy and constant activity had made him well-suited to the military life."
