William Aislabie of Studley Royal, North Yorkshire was an English landowner and Tory politician who sat in the House of Commons for over 60 years from 1721 to 1781. His long unbroken service in the House of Commons was only surpassed, more than 100 years after his death, by the 63 years achieved by Charles Pelham Villiers at Wolverhampton.

John Aislabie or Aslabie, of Studley Royal, near Ripon, Yorkshire, was a British politician who sat in the English and British House of Commons from 1695 to 1721. He was of an independent mind, and did not stick regularly to the main parties. He was Chancellor of the Exchequer at the time of the South Sea Bubble and his involvement with the Company led to his resignation and disgrace.
