Mohammad-Mehdi Abdekhodaei () is an Iranian conservative activist.
Son of Sheikh Gholamhosein Mojtahed-e Tabrizi, he had a lower-middle-class bazaari background and was a minor attendant in a small hardware store. On 13 February 1952, when he was a 15-year-old member of the Fada'iyan-e Islam, he attempted to assassinate Hossein Fatemi who was delivering a speech at the grave of journalist Mohammad Masud who had been assassinated in 1948. Fatemi survived the shooting. Abdekhodaei was tried as a juvenile and imprisoned for twenty months.
He revived the Fada'iyan-e Islam after the Iranian Revolution, though the organization is not a significant actor.
