Colonel William Henry Foster (1848 – 27 March 1908) was a British businessman and Conservative Party politician, who owned the Black Dyke Mills in the West Riding of Yorkshire and lived in Hornby Castle in Lancashire. He sat in the House of Commons from 1895 to 1900. Career Foster was the son of William Foster, of Hornby Castle, Lancashire and of Queensbury, near Bradford in the West Riding of Yorkshire. He was educated in Liverpool and abroad, and entered the family's textile business, becoming a director in 1842 of John Foster and Son Ltd in Queensbury, and other businesses. The family's Black Dyke Mills, which dominated the village of Queensbury, became one of the world's largest makers of worsted cloth. The firm had been founded by his grandfather John Foster (1798–1879), who had retired to Hornby Castle and passed the company to his son William (1821–1884). Foster was appointed as High Sheriff of Lancashire in June 1891, after the death of George Preston, and in September 1892 he became a Deputy Lieutenant of the West Riding of Yorkshire. He served in the militia as the Lieutenant-Colonel of the 2nd West Yorkshire Yeomanry Cavalry until his retirement in 1892, with the honorary rank of Colonel.

He had been approached in 1893 to stand for Lancaster, but a local meeting selected someone else, and Foster withdrew. However, in August that year another local meeting asked him to stand, and an announcement was made to that effect, but he was not formally adopted as a candidate until 29 June 1895. After his victory on 19 July 1895, an election petition was lodged, alleging that Foster and his election agents were guilty of "bribery, treating and other corrupt practices". The full list of 117 charges (of which 32 were struck out by the judges) included allegations included 26 cases of treating, 14 of bribery, 13 prohibited persons voting, and that Foster had offered voters employment at his mills in Queensbury. In the hearings at Lancaster Castle, Foster denied the charges, telling the court that at a meeting where his record as an employer had been attacked, he had said that work was available at the mills. Judgment was delivered on 24 January, when all the charges against Foster were dismissed and the petitioners
