Red Square, officially Central Plaza or the Suzzallo Quadrangle, is a large open square on the Seattle campus of the University of Washington that serves as a hub for two of the university's major axes, connecting the campus's northern Liberal Arts Quadrangle ("The Quad") with the science and engineering buildings found on the lower campus.

Whether it was also meant to refer to Moscow's Red Square in an era known for student activism is unclear.

The northwest area of the square is dominated by three adjacent brick monoliths; one to ventilate the underground garage and the other two for aesthetic reasons.

The northeast corner of the square features a version of Barnett Newman's Broken Obelisk sculpture.

The plaza is surrounded by the following buildings: Red Square has hosted ESPN's College GameDay three times, in 2013, 2016, and 2023.
