Thomas Rawlinson (1681–1725) was an English barrister, known as a bibliophile.
Born in the Old Bailey in the parish of St. Sepulchre, London, on 25 March 1681, the eldest son of Sir Thomas Rawlinson (1647–1708), by Mary (d. 1725), eldest daughter of Richard Taylor of Turnham Green, Middlesex; Richard Rawlinson was a younger brother. After education under William Day at Cheam, and at Eton College under John Newborough, he matriculated at St John's College, Oxford on 25 February 1699. He left the university in 1701, and studied at the Middle Temple, where he had been entered on 7 January 1696.
Rawlinson was called to the bar on 19 May 1705, and then made a tour through England and the Low Countries. Returning to London, he concentrated on municipal law, but succeeded to a large estate on the death of his father in 1708. He resided for some years in Gray's Inn, where his accumulation of books compelled him to sleep in a passage. In 1716 he hired London House, Aldersgate for his library, stacked three deep. Joseph Addison is supposed to have had Rawlinson in mind when (in The Tatler, No. 158) he wrote on Tom Folio, a "learned idiot".
Rawlinson was elected a governor of Bridewell and Bethlehem Hospital in 1706, and of St. Bartholomew's Hospital in 1712. He became a Fellow of the Royal Society on 19 February 1713, and of the Society of Antiquaries of London in 1724. He married, on 22 September 1724, his servant Amy Frewin, formerly a maid at a coffee-house in Aldersgate Street, and died without issue at London House on 6 August 1725. He was buried in St Botolph's Aldersgate.
