Daniel Massey (24 February 1798 – 15 November 1856) was an American-born Canadian blacksmith and businessman in what is now Newcastle, Ontario. A member of the Massey family and a farm machinery pioneer, Massey began production of agricultural implements in 1847 and established what grew into Massey Ferguson. The family relocated to Upper Canada sometime between 1802 and 1807, likely to acquire cheap land, as many Americans were doing at the time.
In 1844, Massey's son Hart took over the farm, while Massey himself tinkered with repairing implements in a workshop on the property. which produced the world's first commercially successful self-propelled combine harvester in 1938. Massey-Harris purchased the Ferguson Company in 1953 to form Massey-Harris-Ferguson, which was shortened to Massey Ferguson in 1958.
Massey was inducted into the Ontario Agricultural Hall of Fame in 1981 after being nominated by Massey Ferguson. and is buried at Bowmanville Cemetery in Clarington, Ontario.
Lillian Massey Treble was Massey's granddaughter and Edward Wentworth Beatty was his grandson via daughter Elvira Deborah Massey. His great-grandchildren included Vincent Massey and Raymond Massey, architect Geoffrey Massey, and civil servant Lionel Massey.
