John McGraw (May 22, 1815 - May 4, 1877) was a wealthy New York State lumber merchant, philanthropist, early benefactor and trustee of Cornell University.

John later married Jane P. Bates Turner in Ithaca, Tompkins, New York, in 1861.

Both John and his daughter, Jennie are buried in the crypt at Sage Chapel, Cornell University in Ithaca, New York.

His former business partner, Henry Sage, made a large donation to Cornell in the name of Jennie to replace the lost funds.
