The Quaid-e-Azam House, also known as Flagstaff House, is a house museum dedicated to the personal life of Muhammad Ali Jinnah, the founder of Pakistan. Located in Karachi, Sindh, Pakistan, it was designed by British architect Moses Somake.

This is the former residence of Jinnah, who lived there from 1944 until his death in 1948. His sister, Fatima Jinnah lived there until 1964. It was bought by Jinnah in 1943 at the cost of 115,000 Indian rupees (equivalent to ₹17,466,973 in 2023). The building was later acquired in 1985 by the Pakistani government and converted to a museum.

In 1984, it was converted into the Flagstaff House Museum of great Jinnah.
