Barclay Fowell Buxton (16 August 1860 – 5 February 1946) was an English evangelical Christian missionary in Japan.
Within several weeks of his arrival over 700 people were attending his services and by the end of the first year seven churches had been founded around Matsue and Yonago.
He invited Paget Wilkes to join him as a lay helper in 1897, and the two worked together in Western Japan, before returning to England.
He was an uncle of Arthur Buxton (1882–1958), Chaplain to the Forces and Rector of All Souls Church, Langham Place, Marylebone.
He played at the 1880 Wimbledon Championships where he lost in the first round,[3] and he won the men's singles title at Cambridge University LTC Tournament in 1881 against Erskine Gerald Watson.
