Ammar Jemal (; born 20 April 1987) is a Tunisian professional footballer who plays as a defender. He made 31 appearances for the Tunisia national team scoring six goals.
Jemal was born in M'saken, Tunisia.
On 11 June 2009, Jemal was linked with a move to French club FC Nantes on a four-year contract. This move would have reunited him with his former coach Gernot Rohr, but the transfer was later cancelled. On 7 May 2010, he announced his resignation from Etoile du Sahel and signed with BSC Young Boys. Jemal started the first leg of their Champions League Playoff against Tottenham Hotspur because of an injury to regular center back Emiliano Dudar.
On 30 August 2011, Jemal went on loan to 1. FC Köln for one year followed by a call back and buy option.
