John Labatt (11 December 1838 – 27 April 1915) was a Canadian businessman and brewer.
Labatt was born in Westminster Township, near London, Ontario, Upper Canada, and was the son of Eliza (Kell), from Bradford, England, and John Kinder Labatt, who came from Ireland and was the founder of the Labatt Brewing Company. He attended Trinity College School in Port Hope, Ontario, graduating in 1896.
When the elder Labatt died in 1866, John assumed control of the company. Under his supervision, it grew to be the largest brewery in Canada. Following his death, the company was controlled by a trust operated by his nine children, although his sons John Sackville Labatt and Hugh Francis Labatt assumed managerial control.
Labatt died in 1915.
His wife was Catherine Maria Biddulph. His great-grandson was actor Graham Jarvis.
