John Davenport (April 9, 1597 – May 30, 1670) was an English Puritan clergyman and co-founder of the American colony of New Haven.
Born in Coventry, Warwickshire, England to a wealthy family, Davenport was educated at Oxford University. He matriculated at Merton College in 1613 but migrated to Magdalen College two years later, eventually leaving Oxford before completing his degree.
His father was Henry Davenport (d. May 29, 1627), draper, alderman, and Mayor of Coventry, son of Edward Davenport, Mayor of Coventry. His mother was Winifred Barnaby (1569 - April 12, 1597).
After serving as chaplain of Hilton Castle, he became curate of St Lawrence Jewry in London. In 1624, he was chosen vicar of St. Stephen’s Church, in Coleman Street, London. In 1625, he returned to Oxford for further studies, receiving an MA and BD. He became an associate of John Preston, a leading Puritan teacher and scholar, and edited his works for posthumous publication. His efforts to organize the re-purchase of "lay-impropriations" for the support of rural clergy were frustrated by Bishop William Laud and condemned by the Court of Exchequer, as were also his efforts for the relief of Reformed clergy displaced by war in the Electorate of the Palatinate. In 1633 he resigned from the established church and moved to Holland.
