王府井大街是位于中国北京市东城区中部的一条大街，也是北京市的著名商业街，全长1.8公里，其中南段是王府井步行街。

王府井大街北起美术馆东街南端，与五四大街、东四西大街连接，南至东长安街，与台基厂大街连接。

元大都时期，这条街名为“丁字街”。明朝称“王府街”。明朝永乐十五年（1417年）在此街东侧修建了十王府后，此街改名为“十王府街”，又称“王府街”。 清朝雍正十二年（1734年），在十王府处改建贤良寺，但“王府街”的名称则获得保留。清朝光绪三十一年（1905年)，清政府“推行警政”、“整理地面”，对京师部分街巷名称重加厘定，将“王府大街”改为“王府井大街”。因街西有一甜水井，故名“王府井大街”。

Wangfujing (Chinese:王府井; pinyin:Wángfǔjǐng; literally: "Prince's Mansion Well") is one of the most famous shopping streets of Beijing, China, located in Dongcheng District. The majority of the main area is pedestrianised and very popular shopping place for both tourists and residents of the capital. Since the middle of the Ming Dynasty there have been commercial activities in this place. In the Qing Dynasty, ten aristocratic estates and princess residence were built here, soon after when a well full of sweet water was discovered, thereby giving the street its name "Wang Fu" (princely residence), "Jing" (well). Many exotic foods are served on Wangfujing snack street.
