John Cooke (1824–1882) was one of the principals of Cooke Locomotive Works, one of the constituent companies that made up American Locomotive Company in the merger of 1901.
Cooke was born in Montreal, Quebec, Canada, but sought his fortune in the United States.
His apprenticeship worked out so well for the two of them that he was promoted to shop superintendent by 1843, a position he held until 1852.
When he left Rogers' employ, Cooke formed a partnership with Charles Danforth.
Cooke's company became a serious competitor in the locomotive building business.
