There have been three baronetcies created for people with the surname Riddell, one in the Baronetage of Nova Scotia, one in the Baronetage of Great Britain and one in the Baronetage of the United Kingdom. As of 2014 one creation is extant. The Riddell Baronetcy, of Walton in the County of Surrey, was created in the Baronetage of the United Kingdom on 31 January 1918 for George Allardice Riddell. Sir George was a prominent newspaper proprietor who was subsequently created Baron Riddell. Thus the baronetcy became a subsidiary title until it became extinct on his death in 1934.
