The Old Man House was the largest winter longhouse in what is now the U.S. state of Washington, once standing on the shore of Puget Sound. It was the center of the Suquamish village of dxʷsəq̓ʷəb on Agate Pass, just south of the present-day town of Suquamish. At one time, it was home to the famous Suquamish chiefs Kitsap and Seattle (who was also half Duwamish).
