John la Zouche, 7th Baron Zouche, 8th Baron St Maur

John la Zouche, 7th Baron Zouche, 8th Baron St Maur (1459–1526) was a Yorkist nobleman who was noted for his loyalty to Richard III, under whose command he fought at the Battle of Bosworth, where Richard was killed. Under the victorious Tudor dynasty he suffered attainder and forfeiture of much of his property, but he was eventually restored to royal favour, due partly to a fortunate marriage connection to the new King's mother.

John la Zouche was the son of William la Zouche, 6th Baron Zouche and his first wife, Katherine Lenthall, daughter of Sir Rowland Lenthall, Sheriff of Herefordshire and his wife Lucy Grey, daughter of the 4th Baron Grey of Codnor. His father had inherited the barony of St Maur through his mother Alice St Maur, first wife of William la Zouche, 5th Baron Zouche (c. 1402 – 1462), and daughter of Sir Richard St. Maur (died 6 January 1409) by Mary Pever, the daughter of Thomas Pever (died 22 September 1429).

After the death of Alice St Maur, the 5th Baron married Elizabeth St. John, whose half-sister was Margaret Beaufort, mother of the future Henry VII, a connection which later proved of great value to his grandson.

Zouche's mother seems to have died soon after his birth; his father died when he was nine. His stepmother, Katherine Plumpton, remarried Sir Gilbert Debenham, a Suffolk landowner who acquired considerable influence at the Court of Edward IV. Other family connections strengthened the tie to the House of York: Elizabeth, Lady Zouche, after the 5th Baron's death, remarried John Scrope, 5th Baron Scrope of Bolton, who was to be a strong supporter of Richard III. John's sister Margaret married Sir William Catesby, who was to be one of the mainstays of Richard's government.
