John James (1672-1746) was an architect particularly associated with Twickenham in west London and the design of church buildings - a vocation perhaps partly explained by his being the son of a Hampshire parson, also named John James.

The young John attended the Holy Ghost School, Basingstoke, of which his father was headmaster. He was then apprenticed to the royal carpenter, Matthew Bancks, whose niece he married, and lived for a while at Hampton Court Palace.

Among several buildings in and around Twickenham, John James designed the nave of St Mary's Church after it collapsed in 1713. Slightly further afield, he was responsible for recasing the tower of St Alfege's Church in Greenwich, London after it became unsafe (the tower was the only remaining part of an older church, the rest having also collapsed and been replaced by a new church designed (c.1714) by Nicholas Hawksmoor). James built St Mary's Rotherhithe in 1714 – 1715.

Also in south-east London, James designed a Palladian-style mansion for Sir Gregory Page at Wricklemarsh in 1723; this was demolished in 1787 and the site now forms part of the Cator Estate at Blackheath.
