Sayyed Abol-Ghasem Mostafavi-Kashani (Persian: سید ابوالقاسم کاشانی Abu’l-Qāsem Kāšāni; 19 November 1882 – 13 March 1962) was an Iranian politician and Shia Marja.

[1] His father, Ayatollah Hajj Seyyed Mostafavi Kashani (Persian: آیت‌الله حاج سید مصطفوی کاشانی), was a noted scholar of Islam in his time.

[2] His son Mostafa died in an accident in 1955; the newly appointed prime minister, Hossein Ala', escaped an assassination attempt at the funeral.

[8][9] Kashani served as speaker of the Majles (or lower house of Parliament), during the oil nationalization, but later turned against Mosaddeq during the 1953 Iranian coup d'état.

Kashani protected the violent Islamist group Fada'iyan-e Islam, led by Navvab Safavi, after their expulsion from the Qom seminary by Ayatollah Hosein Borujerdi in 1950.
