Baron Gretton, of Stapleford in the County of Leicester, is a title in the Peerage of the United Kingdom. It was created in 1944 for the brewer and Conservative politician John Gretton. He was head of the brewery firm of Bass, Ratcliff & Gretton Ltd of Burton upon Trent and also represented Derbyshire South, Rutland and Burton in Parliament. His son, the second Baron, also represented Burton in the House of Commons as a Conservative. As of 2010[update] the title is held by the latter's grandson, the fourth Baron, who succeeded his father in 1989. His mother, Jennifer Gretton, Lady Gretton, has been Lord Lieutenant of Leicestershire since 2003.
The family seat was Stapleford Park, Leicestershire. American fast-food restaurateur and hotelier Bob Payton bought it in 1988 to convert into a hotel. He restored the buildings, according to his obituary "hiring Wedgwood, Turnbull & Asser, Crabtree & Evelyn to decorate its rooms".
