Sidney Harman Hall is a theater at Sixth and F Streets NW in Washington, D.C.

Built for $89 million, the building was designed by Paul Beckmann of the DC firm Smithgroup; the theater itself by Toronto architect Jack Diamond.

The walls of the theater are panels of makore, an African wood; velour curtains behind the panels can be raised to alter the room's acoustics.

From October 25–28, 2010, Sidney Harman Hall hosted The Daily Show with Jon Stewart, including the October 27 show whose guest was President Barack Obama.
