The Qasim Ali Khan Mosque (Urdu, Pashto: مسجد قاسم علی خان); (Hindko: قاسم علی خان مسیت) is a 17th-century mosque in Peshawar, Khyber Pakhtunkhwa, Pakistan.

The mosque was built during Emperor Aurangzeb's reign (1658 to 1707), by Qasim Ali Khan, a news writer and administrator in the government of Kabul.

The legend has been passed down through generations of residents, creating a conflict amongst scholars and historians concerning the real builders' identities.

He was the first to lay a road through the Khyber Pass and was later appointed governor of Kabul and Peshawar.

Mufti Abdur Rahim Popalzai II published a journal by the name of Sarfaroosh and was part of the freedom movement against the British.
