Ahmad Zia Massoud () (born May 1, 1956) was the Vice President of Afghanistan in the first elected administration of President Hamid Karzai, from December 2004 to November 2009. He is a younger brother of Ahmad Shah Massoud, the legendary resistance leader against the Soviet invasion of Afghanistan and against the Taliban. In late 2011, Ahmad Zia Massoud joined hands with major leaders in the National Front of Afghanistan which strongly opposes a return of the Taliban to power. The National Front is generally regarded as a reformation of the United Front (Northern Alliance) which with U.S. air support removed the Taliban from power in late 2001.
