Redeemer Seminary (also known as Redeemer Theological Seminary or the Westminster Texas Campus) is an Evangelical, Reformed, Christian theological seminary based in Dallas, Texas with branches in Houston and Austin.

Since 1929 Westminster Theological Seminary has been training "specialists in the Bible" who minister the gospel worldwide. In 1999 Westminster began a Texas Campus to extend the knowledge of the glory of God in Christ through offering theological education grounded in the seminary's core values and serving churches and communities in the Southwestern United States. By God's grace, the Texas Campus has graduated students who now serve churches and ministries across the United States. In 2009 Westminster Theological Seminary launched its Texas Campus as Redeemer Seminary, an independent institution which shares the core values and theological commitments upon which Westminster was founded. Westminster concludes its M.Div. and M.A.R. programs in Texas in cooperation with Redeemer during the transition. New students enroll as Redeemer Seminary students.

The purpose of Redeemer Seminary is to form men for the gospel ministry, who shall truly believe, and cordially love, and therefore endeavor to propagate and defend, in its genuineness, simplicity, and fullness, the gospel of our Lord Jesus Christ as revealed in the inerrant and infallible Word of God and summarized in that system of religious belief and practice which is set forth in the Westminster Confession of Faith and Catechisms and which is integrally related to the fundamental principles of Presbyterian church government; thereby, cultivating and sustaining genuine Christian devotion with sound learning.
