McCormick Theological Seminary is a private Presbyterian seminary in Chicago, Illinois. As of 2023, it shares a campus with the Lutheran School of Theology at Chicago and Catholic Theological Union, in the Hyde Park neighborhood of Chicago. A letter of intent was signed on May 5, 2022, to sell the formerly shared campus with the Lutheran School of Theology at Chicago to the University of Chicago. The agreement allows the two seminaries to lease back facilities on the campus. Although it primarily serves the Presbytery of Chicago and the Synod of Lincoln Trails, McCormick Theological Seminary also educates members of other Christian denominations.

The Presbyterian Church (USA), abbreviated PCUSA, is a mainline Protestant denomination in the United States. It is the largest Presbyterian denomination in the country, known for its progressive stance on doctrine and its ordaining of women and members of the LGBT community as elders and ministers. The Presbyterian Church (USA) was established with the 1983 merger of the Presbyterian Church in the United States, whose churches were located in the Southern and border states, with the United Presbyterian Church in the United States of America, whose congregations could be found in every state.
