William Osbaldeston (1631–1707) was an English politician who served as Member of Parliament for Scarborough.
William was born in York, and baptised at St Martin's, Coney Street on 10 June 1631.
[3] In Yorkshire, Osbaldeston served as a justice of the peace, a commissioner, and a deputy lieutenant.
In 1687, King James II demanded that all justices of the peace answer whether they would consent to the repeal of the Test Act and Penal Laws, as the king wished; Osbaldeston gave evasive answers, was removed as deputy lieutenant, and is not known to have stood for Parliament again.
