Mohammad Hasan Khan E'temad os-Saltaneh (Persian: محمدحسن خان اعتماد السلطنه; 1843–1896) was an Iranian statesman, scholar, and author active during the reign of the Qajar shah (king) Naser al-Din Shah Qajar (r. 1848–1896).

[1] He was the son of Ali Khan Maragha'i, a member of the Moqaddam tribe who served as the farrash-bashi (court minister) during the early reign of Naser al-Din Shah.

[2] E'temad os-Saltaneh's secret notebook, entitled Ruz-nama-ye khaterat-e E'temad-al-Saltana, which spans over 17 years of his career, is considered his most significant work and one of the most important sources for the history of the late Qajar period.

[2] E'temad os-Saltaneh, like many of the European-educated politicians of that era, supported a sort of "enlightened" monarchy that was committed to strong governance and advancement in technology but also took into account the interests of the traditional nobility.

Frequently, he expressed his dissatisfaction that Naser al-Din Shah was more preoccupied with the dramatic and enjoyable elements of European media and publications than with their important historical and ethical worth.
