John Beauchamp, 1st Baron Beauchamp (fifth creation)

John Beauchamp, 1st Baron Beauchamp (fifth creation) (c. 1319 – 1360) was an English nobleman and soldier. He was a Knight of the Garter and a prominent figure in the service of King Edward III.

Born into the Beauchamp family, he was the son of Guy de Beauchamp, 11th Earl of Warwick, and Alice de Toeni. He was summoned to Parliament as Baron Beauchamp of Warwick on 29 November 1337, creating the fifth barony of Beauchamp. This creation was distinct from the earldom held by his nephew, Thomas de Beauchamp, 12th Earl of Warwick.

Beauchamp served with distinction in the King's wars in France, participating in campaigns throughout the 1340s and 1350s, including the Battle of Crécy (1346) and the Siege of Calais. He was a trusted military commander and frequently served in the retinue of Edward, the Black Prince.

In 1344, he was one of the founding knights of the Order of the Garter, a prestigious order of chivalry established by Edward III. This honor reflects Beauchamp's standing at court and his reputation for martial prowess.

John Beauchamp married Margaret de Saint John, daughter of John de Saint John, 2nd Baron Saint John of Basing, and Isabel de Courtenay. They had no surviving male issue, and upon his death in 1360, the barony became extinct. His lands and titles were inherited by his daughters and their descendants. His death pre-dated that of his nephew, the 12th Earl of Warwick, and thus he never held the earldom himself. He is buried in the collegiate church of St Mary, Warwick.
