John Sadler (of Warmwell) (18 August 1615 – April 1674) was an English lawyer, academic, Member of Parliament, Town Clerk of London, Hebraist, Neoplatonist and millenarian thinker, private secretary to Oliver Cromwell, and member of the Parliamentarian Council of State. He was Master of Magdalene College, Cambridge from 1650 to 1660.

Sadler was educated at Emmanuel College, Cambridge.

He married Jane, daughter of the Dorset MP John Trenchard. His sister Ann married John Harvard.

He was nominated for Cambridgeshire for the 1653 Barebone's Parliament. In 1659, for the Third Protectorate Parliament, he was MP for Yarmouth, in the Isle of Wight.

Ernestine van der Wall writes:

The Hale Commission on law reform, headed from 1652 by Sir Matthew Hale, had Sadler as a leading lawyer, together with William Steele and John Fountain.

He was Town Clerk of London from 3 July 1649 (elected) to 18 September 1660. He was removed on the Restoration, under the pretext that he had signed the death warrant of Christopher Love. He was suspended 4 September 1660, then the suspension was removed on 6 September 1660 and finally he was "declared incapable of office" on 18 September 1660.
