Ahmad II ibn Ali (13 April 1862 – 19 June 1942) (Arabic: أحمد باي بن علي باي, ʾAḥmad Bāy bin ʿAlī Bāy) was the ruler of Tunisia from 11 February 1929 until his death. He was the son of Ali Muddat ibn al-Husayn.
He was born in the Dar al-Taj Palace at La Marsa. On 14 January 1928 he became the Bey al-Mahalla (crown prince) of Tunis, and thus the lieutenant-general of the Beylical Army, and became bey upon the death of his cousin Muhammad VI al-Habib.
Ahmad died at La Marsa and was buried at the Turbat al-Bey. He was succeeded by his cousin Muhammad VII al-Munsif.
Ahmad II had ten sons and eight daughters, including Prince Muhammad al-Taib Bey (1902-1989) who was the head of the Husainid Dynasty from 1974 until 1989.
