Yongdingmen (; Manchu: Enteheme toktoho duka) was the former front gate of the outer section of Beijing's old city wall. Originally built in 1553, it was torn down in the 1950s to make way for the new road system in Beijing. In 2005, the Yongdingmen was reconstructed at the site of the old city gate. This new gate is disconnected from the original road leading towards the gate and into the city (see photograph below).
During the Boxer rebellion, on 11 June, the secretary of the Japanese legation, , was attacked and killed by the Muslim soldiers of General Dong Fuxiang near Yongdingmen, who were guarding the southern part of the Beijing walled city.
