The Douglas M. and Grace Knight House, also known as Knight House, is a Modernist-style mansion in Durham, North Carolina. The house, designed by Alden B. Dow, previously served as the official residence for presidents of Duke University and is now used by the university as an event space, conference facility, and guest house. On April 6, 1968, following the assassination of Martin Luther King Jr., four-hundred and fifty university students marched to the house during the Silent Vigil at Duke University to deliver a list of demands to Duke president Douglas M. Knight. The house, previously called University House, was officially named after Knight and his wife, Grace Nicholas Knight, in 2003.
