Avery Cornburgh (1430 – 2 February 1487) was an English politician and sea captain who was Under-Treasurer of England from 1483 to 1487 and Keeper of the Great Wardrobe in the Royal Household from 1486 to 1487.

Career He was a Member (MP) of the Parliament of England for Cornwall 1463 and 1467 and probably also for a Cornish seat in 1472–5. He was MP for Plymouth in 1478, 1483, 1485 and also probably also for a Cornish seat in 1484.

In the Royal Household, he was a Yeoman of the Crown and Chamber from 1455 to 1474 then an Esquire of the Body and Sea captain from 1474 to 1485. He was Under-Treasurer of England 1483–87 and Keeper of the king's Great Wardrobe from 1486 to 1487. He was JP for Cornwall from 1463 and Essex from 1468, sheriff of Cornwall in 1464–5 and 1468-9 and sheriff of Essex and Hertfordshire 1472–3 and 1477–8. He was responsible for buying the ship the 'John Evangelist' in Dartmouth for the Royal Navy in 1463. He was also sea captain of the ship the 'Grace Dieu' in 1480. Margaret Connolly writes:She was the daughter of London citizens, William and Alice Lynne. Her father, variously described as a ‘wolmongere’, merchant, and grocer, died in 1421, leaving all of his property to his wife who subsequently took a vow of chastity. At the time of his death his five children, John, Robert, Margaret, Alice, and Beatrice, were all minors. Nothing further is known of Robert who may have died before he reached maturity, but the fortunes of the four other children can be easily traced. John and Alice both subsequently married into the Knyvett family of Norfolk, John acquiring the Knyvett ancestral home of Southwick via his wife, either as her dowry or perhaps by purchase. John Lynne's wife was Joan, one of the daughters of Sir John Knyvett and Elizabeth, daughter of Constantine, 2nd Lord Clifton (1372–95) of Buckenham Castle. Alice Lynne married Sir John's son and heir, also named John Knyvett (1416–91). Margaret Lynne became the second wife of the London scribe John Shirley who died in 1456.

Avery Cornburgh lived at Dover's in Essex and Bere Ferrers in Devon. He owned Hatters, Dagenham from 1482 to 1487. He also lived at Gooshays, Essex.

He died on 2 February 1487 and was buried at Romford, Essex. One of the executors of his will was his nephew-by-marriage Sir William Knyvett.
