日比谷（日比谷）是日本东京都区部的一个地区，主要位于东京都千代田区有乐町至内幸町一带，以日比谷通为中心。日比谷公园、日比谷站、日比谷濠皆位于日比谷，皇居距离日比谷不远。

德川幕府入江户城后对附近湿地进行填埋，此地从田园渔村转变为大名屋敷林立的地区。明治维新以后，日本最早的西洋式饭店帝国饭店、鹿鸣馆、东京府厅和社交俱乐部东京倶乐部等陆续设立，成为象徴近代化的街区。明治时代作为上流阶级的社交场所发展，此后剧场、旅馆、大企业本社等陆续进驻，成为日本具代表性的办工商区。

Hibiya(日比谷) is a geographic name covering a part of Chiyoda Ward in Tokyo. The area along Hibiya Street (National Route 1) from Yūrakuchō to Uchisaiwaichō is Hibiya district. Hibiya is used in some local place names such as Hibiya Park and Hibiya Station. Hibiya was a ward named Kōjimachi before Tokyo City was restructured. The outskirts of this district are reclaimed from the ocean, so the name of "hibi" of Hibiya is derived from the facility for the laver of nori made of bamboo whose name is also "hibi".
