Robert Knight Rudolph (June 8, 1906 — July 14, 1986) was an American Reformed Episcopal minister and theologian.

Together Rudolph and his father trained men for the gospel ministry at this institution for a total of seventy-four years.

After attending the Collegiate School in New York, Rudolph earned his undergraduate degree at the University of Pennsylvania in 1929.

Rudolph began teaching at Reformed Episcopal Seminary that year and continued his studies at Westminster, where he received a Master of Theology degree.

In 1949, he was asked by William B. Eerdmans Publishing Company to write an Introduction for its printing of John Calvin's commentary on the book of Genesis.
