Kenneth S. Kantzer (March 29, 1917 – June 20, 2002) was an American theologian and educator in the evangelical Christian tradition.
Kantzer, having studied at Faith Theological Seminary, Trinity Seminary and Bible College, and earned a Ph.D. in Philosophy and Religion from Harvard University (1950), was a professor of biblical and systematic theology and academic dean of Trinity Evangelical Divinity School (TEDS) from 1960 to 1978.
There he helped to grow TEDS from a small denominational seminary to a major evangelical Christian graduate school with a national and international reputation.
From 1977 to 1982, he was editor of Christianity Today, and, from 1982 to 1984, was president of Trinity College in Deerfield, Illinois.
Through his teaching and his leadership at TEDS and his work at Christianity Today, Kantzer made a significant contribution to the growth of evangelicalism for more than forty years.
