John D. Whitney (July 19, 1850 – November 27, 1917) was an American Catholic priest who was the president of Georgetown University from 1898 to 1901. Born in Massachusetts, he joined the United States Navy at the age of sixteen. He became a Jesuit in 1872 and spent the next twenty-five years studying and teaching mathematics at Jesuit institutions in Canada, England, Ireland, and the United States. He became the vice president of Spring Hill College in Alabama before becoming the president of Georgetown. He oversaw the completion of Gaston Hall, the construction of the entrances to Healy Hall, and the establishment of Georgetown University Hospital and what would become the School of Dentistry. Afterwards, Whitney became the treasurer of Boston College and then engaged in pastoral work in Philadelphia, Brooklyn, and Baltimore, where he became the prefect of St. Ignatius Church.
