Louis Berkhof (13 October 1873 – 18 May 1957) was a Dutch-American Reformed theologian whose works on systematic theology have been influential in seminaries and Bible colleges in the United States, Canada, Korea and with individual Christians in general throughout the 20th century.

In 1900, he graduated from the seminary in Grand Rapids after which he was appointed pastor of the First Christian Reformed Church in Allendale Charter Township, Michigan.

Berkhof was not known for being original or speculative but for being very good at organizing and explaining basic theological ideas following in the tradition of John Calvin, Abraham Kuyper and Herman Bavinck.

They are organized for use in seminaries and religious education as well as individual reference, though his systematics works are demanding reads.

One of the prominent students of Berkhof is Cornelius Van Til, whose thoughts became the major position of the tradition of Westminster Theological Seminary in the areas of apologetics and epistemology.
