St John Street is a street in central Oxford, England. The street mainly consists of Georgian-style stone-faced Grade II listed terraced houses. It was built as a speculative development by St John's College starting in the 1820s and finishing in the 1840s at the start of the Victorian era.
At the northern end is Rewley House (housing Oxford University's Department of Continuing Education) and near the southern end is the Sackler Library, which opened in 2001. To the south is Beaumont Street and to the north is Wellington Square. St John Street runs parallel with St Giles' (linked via Pusey Street) to the east and Walton Street to the west.
Note that part of Merton Street was once known as St John Street.
The Oxfordshire-born painter William Turner (1789–1862) lived at No. 16 from 1833 until his death. The house is marked with a blue plaque.
Other famous residents of St John Street have included the theologians Henry Chadwick and Arthur Peacocke; authors P. D. James, Iain Pears and J. R. R. Tolkien; and musician Thom Yorke.Ludwig Wittgenstein also lived there towards the end of his life.
