Thomas Bourchier (1404 – 30 March 1486)[1] was a medieval English cardinal, Archbishop of Canterbury, and Lord Chancellor of England.

In 1458 he helped to reconcile the contending parties as part of The Love Day, but when the war was renewed in 1459 he had become a decided Yorkist.

[3] In 1457 Bourchier took the chief part in the trial for heresy of Reginald Pecock, Bishop of Chichester.

After the death of King Edward IV in 1483 Bourchier persuaded the queen to allow her younger son, Richard of Shrewsbury, 1st Duke of York, to join his elder brother King Edward V in (supposedly protective) residence in the Tower of London.

[3] Bourchier died on 30 March 1486[6] at the palatial residence he had transformed, Knole House, near Sevenoaks in Kent, and was buried in Canterbury Cathedral, where his monument can be found.
