Douglas Maitland Knight (June 8, 1921 – January 23, 2005) was an American educator, businessman, and author. He was a former professor of literature at Yale University prior to his presidency at Lawrence College from 1954 to 1963. Stemming from his work at Lawrence College was his subsequent term as president of Duke University, where he served until he resigned in 1969 following student protests and the takeover of the university's main administrative building by students calling for a black cultural center and African-American studies program, among other things. Controversy over these issues led to his transition into the business world at RCA and Questar Corporation. Knight never fully retired, and was known to consult for Questar's Board of Trustees years after his departure.
