Tsapan is a floating city on the planet Kinahhi.
Tsapan proved to be the location of the Kinahhi's sheh-fet technology. The device was destroyed by O'Neill and the city was destroyed during a battle with the Kinahhi military. SG-1 and their allies managed to steal a transport ship docked with the city and fled to the mainland where they linked up with reinforcements from Earth led by General Hammond.
