William Henry Forester Denison, 1st Earl of Londesborough (19 June 1834 – 19 April 1900), known as The Lord Londesborough from 1860 to 1887, was a British peer and Liberal politician. He was also one of the main founders of Scarborough FC.
He was elected to the House of Commons for Beverley in 1857, a seat he held until 1859, and then represented Scarborough from 1859 to 1860 when he succeeded his father in the barony and entered the House of Lords.
In 1887, he was created Viscount Raincliffe, of Raincliffe in the North Riding of the County of York, and Earl of Londesborough, in the County of York. He was appointed Honorary Colonel of the 4th East Riding Artillery Volunteer Corps on 11 August 1860 and of the 1st Yorkshire (East Riding) Rifle Volunteer Corps (later 1st Volunteer Battalion, East Yorkshire Regiment) on 24 April 1862. The Volunteers' drill hall in Hull was named Londesborough Barracks in his honour. He transferred from the 1st Bn to be Hon Col of the 2nd Volunteer Battalion, East Yorkshire Regiment on 9 September 1893.
Earl Londesborough was also the Worshipful Master of the Constitutional Lodge No. 294 in Beverley.
The Earl was also the first President of the British Goat Society established in 1869.
The Earl entertained Edward VII at his villa, Londesborough Lodge at Scarborough in 1871. The 'Londesborough Theatre' (1871-1960) was named in his honour. Both Raincliffe Woods, and the former Raincliffe School, were also named after the title bestowed on him in 1887.
