William la Zouche, 1st Baron Zouche (1276/86–1352), lord of the manor of Harringworth in Northamptonshire, was an English baron and soldier who fought in the Wars of Scottish Independence. He is referred to in history as "of Harringworth" to distinguish him from his first cousin (of the senior line) Alan la Zouche, 1st Baron la Zouche (1267–1314) of Ashby de la Zouch in Leicestershire.

William was the son of Eudo la Zouche (d. 1279) by his wife Millicent de Cantilupe (d. 1299), widow of John de Mohaut, daughter of William III de Cantilupe by his wife Eva de Braose, 3rd daughter and co-heiress of William de Braose, Baron Bergavenny.^[5] Millicent de Cantilupe was a great heiress, being a co-heir to her brother George de Cantilupe (d. 1273), Baron Bergavenny, feudal baron of Totnes in Devon (formerly held by de Braose), she was heiress of the English feudal barony of Eaton Bray (formerly held by Cantilupe) and of the manor of Harringworth, amongst many other lands.^[6]

William's younger brother was Roger la Zouch, Lord of Lubbesthorpe (d. 1303), father of Roger la Zouch the instigator of the murder of Roger de Beler in 1326. William's sister, Eva la Zouch, was married to the rebel Maurice de Berkeley, 2nd Baron Berkeley who was imprisoned in Wallingford Castle and died there also in 1326.

William inherited the manor of Harringworth, including a park and wood, upon the death of his mother Millicent de Cantilupe in 1299.^{[2][non-primary source needed]}

William was summoned to Parliament by writ as Baron Zouche of Harringworth from 1308 to 1325^{[7][non-primary source needed]} and to serve against the Scottish from 1314 (after the disastrous Battle of Bannockburn) to 1317.^{[7][non-primary source needed]}

William was pardoned for his role in the death of Piers Gaveston in October 1313^{[7][non-primary source needed]} but made a Conservator of the Peace in Northamptonshire from 1317 to 1321 and ordered to suppress illegal meetings.^{[7][non-primary source needed]}

In February 1322, William was ordered to muster as many men-at-arms and foot soldiers as he could and to march to the King to aid in the suppression of the rebels of Thomas, 2nd Earl of Lancaster.^{[7][non-primary source needed]} William declined and sent two men-at-arms in June, claiming ill health as his excuse.^{[7][non-primary source needed]}

Later in 1322, William was summoned to serve against the Scots and against Lancaster's rebels.^{[7][non-primary source needed]} He was summoned to defend Aquitaine in 1324, which was lost under the poor leadership of Hugh le Despenser, 1st Earl of Winchester, and to go to Gascony in 1325.^{[7][non-primary source needed]}

After Queen Isabella and Roger Mortimer, 1st Earl of March's successful overthrow of her husband, Edward II, William was summoned to the Parliament held in January 1327^{[7][non-primary source needed]} which decided it had lost confidence in the rule of Edward and forced his abdication.

William died on 10 March 1352. Inquisition post mortems found he held land in Shropshire, Wiltshire, Norfolk, Bedfordshire, Buckinghamshire, Rutland, Warwickshire, Leicestershire, Lincolnshire, Northamptonshire and Worcestershire.^{[3][non-primary source needed]}

William married Maud Lovel (d. 1346), daughter of John Lovel, 1st Baron Lovel of Titchmarsh.^[8]
