Yale University Press is the university press of Yale University. It was founded in 1908 by George Parmly Day and Clarence Day, grandsons of Benjamin Day, and became a department of Yale University in 1961, but it remains financially and operationally autonomous.

A university press is an academic publishing house specializing in monographs and scholarly journals. They are often an integral component of a large research university. They publish work that has been reviewed by scholars in the field. They produce mainly academic works but also often have trade books for a lay audience. These trade books also get peer reviewed. Many but not all university presses are nonprofit organizations, including the 160 members of the Association of University Presses.
