John Dwight Pentecost (April 24, 1915 – April 28, 2014) was an American Christian theologian, best known for his book Things to Come.

Pentecost was born in Pennsylvania and died in Dallas, Texas. His wife was Dorothy Harrison Pentecost (June 17, 1915 – June 21, 2000). John and Dorothy had two daughters: Jane Pentecost Fenby and Gwendolyn Ann Pentecost Arnold.

He held a B.A. from Hampden-Sydney College (1937), in addition to Th.M. (1941) and Th.D. (1956) degrees from Dallas Theological Seminary. During his academic career he taught biblical subjects for over 60 years (Philadelphia College of Bible, 1948–55; Dallas Theological Seminary, 1955-2014). His nearly twenty books are written mostly for the general Christian reader. His pastoral career continued through this period.
