Sir Timothy Turner SL JP (11 July 1585 – January 1677) was an English judge.
In the contemporary debates between Sir Edward Coke and Lord Chancellor Ellesmere, Turner's notebooks reveal him to have felt a strong reaction against Ellesmere's claims for the royal prerogative as "transcendent to the common law".
His initial practice was centered on Ludlow, the legal center of Wales and the Marches, but he was of little note officially until 1626, when he became a justice of the peace for Shropshire, through the influence either of Sir Thomas Coventry, or Ellesmere's son and heir the Earl of Bridgewater.
A commissioner in Shropshire for the forced loan of 1626, Turner was subsequently king's solicitor before the Council of the Marches from 1627 to 1637, and a master in chancery extraordinary from 1630.
During the Interregnum, Turner reflected in 1658 that the conflict between Coke and Ellesmere "overthrew all at Last and brought the whole nation...into that slavery".
