Mirza Abolghasem Ghaem Magham Farahani (Persian: میرزا ابوالقاسم قائم مقام فراهانی) or Mirza Abu'l-Qasim Farahani Qá'im Maqam (1779 – June 28, 1835, Negarestan Garden, Tehran) was an Iranian Prime Minister in the early 19th century.
He was born in the city of Arak, Iran. His father, Mirza Isa Ghaem Magham Farahani, had served the Qajar family for more than 20 years. Before being prime minister, he was chancellor of Mohammad Mirza's court. He was later betrayed and murdered on the orders of Mohammad Shah Qajar in 1835, at the instigation of Haji Mirza Aghasi, who would become Ghaem Magham's successor. His books include Monsha'at.[1]
