Catherine or Katherine of York (14 August 1479 – 15 November 1527) was the ninth child and sixth daughter of King Edward IV by his wife Elizabeth Woodville. From birth to death, she was daughter to Edward IV, sister to Edward V, niece to Richard III, sister-in-law to Henry VII and aunt to Henry VIII.
She was born in Eltham Palace. Edward IV hastened to seek a marriage contract for his youngest daughter and on 28 August 1479 a marriage contract was concluded promising Catherine to John, Prince of Asturias, eldest son of Ferdinand II of Aragon and Isabella I of Castile. The alliance was still being negotiated when her father died on 9 April 1483. This marriage was never concluded.
Her brother-in-law Henry VII, husband of her sister Elizabeth, later negotiated with James III of Scotland to obtain a possible husband for her. According to an agreement drawn up in November 1487, Catherine would marry James Stewart, Duke of Ross, second son of James III. The same agreement promised the hand of her mother Elizabeth Woodville to James III and the hand of one of her sisters to the future James IV of Scotland. James III was killed in the Battle of Sauchieburn (11 June 1488). His son and successor, James IV, never pursued this agreement.
By late October 1495, Catherine was already married to William Courtenay (born 1475), created Earl of Devon in 1511. He was the eldest son and heir-apparent of Edward Courtenay, 1st Earl of Devon, and his wife and distant cousin Elizabeth Courtenay. They were parents to three children:
- Henry Courtenay, 1st Marquess of Exeter (c. 1496 – 9 January 1539)
- Edward Courtenay (c. 1497 - 12/13 July 1502);
- Margaret Courtenay (c. 1499 - bef. 1526) married Henry Somerset, 2nd Earl of Worcester
Her husband was attainted in 1504 and thus was unable to succeed his father on 28 May 1509. Her nephew Henry VIII apparently had greater trust for William and created him Earl of Devon on 10 May 1511, however William died on 9 June 1511. He was Earl for less than a full month. Their son Henry succeeded his father, later being created Marquess of Exeter.
As a widow, Catherine reportedly went through periods of both "wealth" and "adversity" (according to Holinshed) but was reportedly favoured by her nephew Henry VIII who "brought her into a sure estate". She outlived her husband by sixteen years before she died at Tiverton Castle aged forty-eight, she was buried next door at St Peter's Church following an elaborate funeral. 
She was the last of Edward IV's children to die.
The arms of Catherine were her husband’s arms impaling her own paternal arms: Baron: Quarterly, first and fourth: or, three torteaux (Courtenay); second and third: or, a lion rampant azure (de Redverd); Femme: quarterly, first: France modern and England, second and third: or, a cross gules (de Burgh), fourth (Mortimer). These arms may be seen, exposed to the elements and thus very worn, sculpted above the south porch of St Peter's Church, Tiverton, Devon.
