Sir William Strickland, 3rd Baronet of Boynton, Yorkshire was an English landowner and Whig politician who sat in the English and British House of Commons between 1689 and 1724. He was also a notable racehorse owner.

Old Sarum was from 1295 to 1832 a parliamentary constituency of England, of Great Britain, and finally of the United Kingdom of Great Britain and Ireland. It was a so-called rotten borough, with an extremely small electorate that was consequently vastly over-represented and could be used by a patron to gain undue influence. The constituency was on the site of what had been the original settlement of Salisbury, known as Old Sarum. The population and cathedral city had moved in the 14th century to New Sarum, at the foot of the Old Sarum hill. The constituency was abolished under the Reform Act 1832.
