William Juxon (1582 – 4 June 1663) was an English churchman, Bishop of London from 1633 to 1646 and Archbishop of Canterbury from 1660 until his death.

In December 1621, he succeeded his friend, William Laud, as President (i.e. head) of St John's College, and in 1626 and 1627 he was Vice-Chancellor of the University of Oxford.

Juxon was deprived of the See of London by Parliament on 9 October 1646, and episcopacy was abolished for the duration of the Commonwealth and the Protectorate.

[8] Juxon, as Archbishop of Canterbury, then took part in the new king's coronation, but his health soon began to fail and he died at Lambeth in 1663.

Juxon House, which stands north-west of St Paul's Cathedral at the top of Ludgate Hill in London and forms part of the Paternoster Square development, is named after him.
