St John's College, Battersea was a teacher training college in Battersea, South London from 1838-1926.
Founded as Battersea College in 1838 by James Kay-Shuttleworth, it was the first teacher training college in England. In 1841 it was renamed St John's College and in 1926 was merged with St Mark's College, Chelsea, with the merged institution, the College of St Mark and St John, based in Chelsea. This college moved to Plymouth in 1973 and is now the University of St Mark and St John.
Originally based in a seventeenth century house, over the life of the college various additional buildings were erected including a chapel to the design of the architect William Butterfield. However the former college buildings were sold to Battersea Borough Council in 1930, which demolished them to make space for council housing. The exception was the original building now known as Old Battersea House, which was saved following a public campaign, and is now a Grade II listed building.
