Thomas Hay, 9th Earl of Kinnoull PC, styled Viscount Dupplin from 1719 to 1758, was a Scottish peer, British politician, and scholar.

Scarborough was the name of a constituency in Yorkshire, electing Members of Parliament to the House of Commons, at two periods. From 1295 until 1918 it was a parliamentary borough consisting only of the town of Scarborough, electing two MPs until 1885 and one from 1885 until 1918. In 1974 the name was revived for a county constituency, covering a much wider area; this constituency was abolished in 1997.
