Darrous (Persian: دروس) is a neighborhood in Shemiran, northern Tehran, Iran. It is considered one of the most affluent areas in the city, as many modern and fashionable families reside there. Darrous is bounded by Pasdaran, Gholhak, Doulat, and Ekhtiyarieh.
Haj Mehdi Gholi Khan Hedayat (Mokhber-ol Saltaneh), a renowned aristocrat of the late Qajar period, was the main land owner in this area prior to 1950s, which at that time consisted of expansive gardens and farms. Beside holding other high offices such as Governor of Fars and Azerbaijan, during the constitutional period, he served from 1927 to 1933 as prime minister during the reign of Reza Shah Pahlavi. His legacy still survives in the area in the form of a mosque, a medical clinic, and a school, all named Hedayat and located on Hedayat Street.
Many foreign embassies are located in Darrous including those of Spain, Hungary, Portugal, Colombia, Argentina and Kazakhstan. In addition, Darrous is home to various United Nations agencies.
