Thomas Clap, American minister and academic (died 1767)

Thomas Clap or Thomas Clapp was an American academic and educator, a Congregational minister, and college administrator. He was both the fifth rector and the earliest official to be called "president" of Yale College (1740–1766). He is best known for his successful reform of Yale in the 1740s, partnering with the Rev. Dr. Samuel Johnson to restructure the forty-year-old institution along more modern lines. He convinced the Connecticut Assembly to exempt Yale from paying taxes. He opened a second college house and doubled the size of the college.
