Baron Newton, of Newton-in-Makerfield in the County Palatine of Lancaster, is a title in the Peerage of the United Kingdom. It was created in 1892 for the Conservative politician William Legh, who had earlier represented Lancashire South and Cheshire East in the House of Commons. Both his son, the second Baron, and his great-grandson, the fourth Baron, were Conservative government ministers. As of 2017[update] the title is held by the latter's eldest son, the fifth Baron, who succeeded in 1992.
