Abbas Tyabji (1 February 1854 – 9 June 1936) was an Indian freedom fighter from Gujarat, who once served as the Chief Justice of the (Baroda) Gujarat High Court. Mahatma Gandhi appointed Tyabji, at age seventy-six, to replace him as leader of the Salt Satyagraha in May 1930 after Gandhi's arrest. Tyabji was arrested soon afterward and imprisoned by the British Indian Government. Gandhi and others respectfully called Tyabji the "Grand Old Man of Gujarat".
