Hasan Ali Khan Garrusi (c. 1820–1900), also known as Amīr(-e) Neẓām Garrūsī or Sālār-e Laškar, was an Iranian diplomat, officer, statesman, and literary figure of the Qajar period.

As part of his education, Hassan Ali Khan was taught Arabic and Persian composition, history, calligraphy and perhaps theology.

[1] As part of the Garrus regiment, Hasan Ali participated in the Herat campaign of 1837/38 and was later assigned to the Tabriz garrison and to pacify the Kermanshah region in 1841/42.

He was then summoned to the capital and chose to leave Bijar for the Shah Abdol-Azim Shrine near Tehran following the suspicious death of his father.

He was charged with patricide but the accession of Naser al-Din Shah Qajar to the throne opened new opportunities for Hasan Ali who was reinstated as commander of the Garrus regiment.
