The National Garden (Persian: باغ ملی, romanized: Bāq-e Melli) or Ministry of Foreign Affairs Gate is a historical and governmental compound in Tehran, Iran.

It was then turned into a public park for a short period, and eventually important governmental offices and museums were built around it.

The range was then developed during the reign of Naser ed Din Shah, with a new building named Cossack House, which was somewhat transformed during the reign of Mozaffar ed Din Shah.

Under the rule of Reza Shah of the Pahlavi dynasty, the range was turned into a modern public park for a short period, and the famous gate of the compound was built by Mirza Mehdi Khan Shaghaghi (Momtahen od Dowle) before World War II.

Eventually, important governmental buildings were built around the compound; such as the "Police House" (or the "Shahrbani House") which was built for the Shahrbani, an organization responsible for maintaining security in the city.
