Muhammad Khaznadar (1840–1929) was an early archaeologist in Ottoman Tunisia. He was the eldest son of Mustapha Khaznadar, a prominent Prime Minister of Tunisia who served from 1855 until 1873.
Khaznadar was the first Tunisian to propose the founding of a museum, located in the Bardo Palace in the town of Manouba just outside Tunis. His collection was to form the kernel of the Bardo National Museum. Khaznadar's work also influenced the development of cultural policies in Tunisia in the years leading up to the establishment of the French protectorate in 1881.
