Baron Gisborough, of Cleveland in the County of York, is a title in the Peerage of the United Kingdom. It was created in 1917 for the Conservative politician Richard Chaloner, who had previously represented Westbury (also known as Wiltshire West) and Abercromby in the House of Commons. Born Richard Long, the son of Richard Penruddocke Long, he had assumed by Royal licence the surname of Chaloner in lieu of Long in 1881, as a condition of inheriting the Guisborough estate and Gisborough Hall from his maternal great-uncle, Admiral Thomas Chaloner. The latter was a descendant through his mother of Robert de Brus, who founded Gisborough Priory in 1119. Lord Gisborough's eldest son and heir Richard Godolphin Hume Long Chaloner was accidentally killed in France in 1917 while guarding German prisoners of war, and is buried at Calais. He was therefore succeeded by his second son, the second Baron. As of 2011[update] the title is held by the latter's son, the third Baron, who succeeded in 1951. He notably served as Lord Lieutenant of Cleveland from 1981 to 1996. The title remains strongly linked with the town of Guisborough.
The prominent Conservative politician Walter Long, 1st Viscount Long, was the elder brother of the first Baron.
The heir apparent is the present holder's son the Hon. Thomas Peregrine Long Chaloner (b. 1961)
