Gregg Alan Mast is a Reformed clergyman, scholar, and seminary president. Mast is the author of six books on Christian practice and theology, and the editor of a collection of sermons by Reformed minister and theologian Howard G. Hageman

Since 2006, Mast has been the fourteenth president of the New Brunswick Theological Seminary located in New Brunswick, New Jersey in the United States—one of two seminaries affiliated with the Reformed Church in America. Mast has overseen the seminary in a time of transition as it built a new, smaller, "technologically smart and environmentally green" campus on College Avenue and Seminary Place in New Brunswick that was completed in 2014. This move—part of a large-scale redevelopment of the College Avenue area of New Brunswick by New Brunswick Development Corporation (DEVCO), Rutgers University and the seminary—was made in response to the seminary's declining enrollment, financial constraints and to replace an aging campus with a modern, environmentally-friendly campus.

Mast was born in 1952 and grew up in Jenison, Michigan. In 1974, Mast earned a Bachelor of Arts (B.A.) degree majoring in religion from Hope College in Holland, Michigan. Pursuing a vocation in the Christian ministry, he received a Master of Divinity (M.Div.) from the New Brunswick Theological Seminary and was ordained as a clergyman in the Reformed Church in America in 1976. He earned a Master of Philosophy (M.Phil.) in 1981 and Doctor of Philosophy (Ph.D.) in Liturgical Studies in 1985 from Drew University in Madison, New Jersey. His doctoral dissertation was titled The Eucharistic Service of the Catholic Apostolic Church and Its Influence on Reformed Liturgical Renewals of the Nineteenth Century (1985) which was later published as a book in 1999.
