Sir Jarrit Smyth, 1st Baronet (1692–1783), previously known as Jarrit Smith, was a British Tory Member of Parliament for Bristol, from 1756 to 1768. He married Florence Smyth, daughter of Sir John Smyth, 3rd Baronet and Elizabeth Asthy. In addition to being a member of parliament, he was also a lawyer and the first to mine the Long Ashton coalfield. In 1748 after various surveys Jarrit Smyth commissioned mine shafts to be dug at South Liberty Lane. In 1760 he carried a bill through Parliament to replace the medieval Bristol Bridge which was in a bad state of repair.
