Dongsi (东四 "Eastern Four" ) is the name of an intersection and surrounding neighborhood in Dongcheng District, Beijing. Dongsi, at the intersection of what is now Dongsi Avenues North, South and West and Chaoyangmen Inner Street, dates to the Yuan dynasty. The intersection is named after four pailou or Chinese sign gates that marked the location and is known in Chinese as the Eastern Four Sign Gates or "Eastern Four" for short.

The sign gates at Dongsi were removed in 1958 but the location names remain. Today, the Dongsi Station on Lines 5 and 6 of the Beijing Subway is located underneath the intersection. Dongsi is also famous for Longfu Temple, a Gelugpa monastery of Tibetan Buddhism that no longer exists. The Longfu Temple Fair was one of the most famous temple fairs in old Beijing. The Dongsi Mosque still exists. It was built in 1356 and rebuilt in 1447. It is located just south of the intersection.

东四是北京市东城区一个十字路口及其周边街区的名称。东四位于今东四北大街、南大街、西大街与朝阳门内大街的交汇处，始建于元代。该十字路口因当时的四座牌楼而得名，中文称之为“东四牌坊”，简称“东四”。
东四的牌坊于1958年被拆除，但地名保留至今。如今，北京地铁5号线和6号线的东四站就位于该十字路口下方。东四也因隆福寺而闻名，这是一座藏传佛教格鲁派寺院，现已不复存在。隆福寺庙会是老北京最著名的庙会之一。东四清真寺至今仍存，它始建于1356年，重建于1447年，位于十字路口正南。
