The Senate (Persian: مجلس سنا, romanized: Majles-e Senā) was the upper house legislative chamber in the Imperial State of Iran from 1949 to 1979.

A bicameral legislature had been established in the 1906 Persian Constitutional Revolution but the Senate was not actually formed until after the 1949 Constituent Assembly election, as an expression of Shah Mohammad Reza Pahlavi's desire for better distribution of power (similar to many democratic countries).

[2] The Senate was disbanded after the Iranian Revolution in 1979, when the new constitution established a unicameral legislature.

Established as per Chapter 3, Article 45 of the Persian Constitution of 1906, The Members of this Assembly shall be chosen from amongst the well-informed, discerning, pious and respected persons of the Realm.

[3] The construction was led by Rahmat Safai, the dome being one of the most technically challenging projects in the entire endeavor.
