Covenant Theological Seminary, informally called Covenant Seminary, is the denominational seminary of the Presbyterian Church in America (PCA). Located in Creve Coeur, Missouri, it trains people to work as leaders in church positions and elsewhere, especially as pastors, missionaries, and counselors. It does not require all students to be members of the PCA, but it is bound to promote the teachings of its denomination. Faculty must subscribe to the system of biblical doctrine outlined in the Westminster Standards.

The Presbyterian Church in America (PCA) is the second-largest Presbyterian church body, behind the Presbyterian Church (USA), and the largest conservative Calvinist denomination in the United States. The PCA is Reformed in theology and presbyterian in government.
