Aliou Cissé (born 24 March 1976) is a Senegalese professional football coach and former player who is the head coach of the Libya national team. Cissé is best known for captaining the Senegal team which reached the 2002 Africa Cup of Nations Final and for being the first Senegal manager to win the tournament in 2022 after reaching the final in 2019.

Having begun his career in France, he later played for English clubs Birmingham City and Portsmouth. Cissé was a defensive midfielder who also, on occasion, played at centre-back.

Cissé has been the head coach of Senegal since 2015, having briefly taken charge of them following Amara Traoré's sacking, in a caretaker role in 2012. He was also the assistant coach of the under-23 side from 2012 to 2013, becoming head coach from 2013 to 2015.

Born in Ziguinchor, Senegal, Cissé moved to Paris at the age of nine, where he grew up with dreams of playing for Paris Saint-Germain. He began his career with Lille before moving onto Sedan and then Paris Saint-Germain. He also spent the majority of the 2001–02 season on loan at Montpellier.

After captaining the Senegal national team to the quarter-finals of the 2002 FIFA World Cup, Cissé transferred to English club Birmingham City for their 2002–03 season, their debut season in the Premier League. Cissé made his first appearance for the club at Arsenal on the opening day of the season, but was sent off. Though the sending-off was rescinded, he went on to receive five yellow cards in six games, ultimately accumulating ten yellow cards before the New Year. His season, however, was cut short after picking up an injury in February that ruled him out for the rest of the season.

Cissé returned late to pre-season training in July 2003, which led manager Steve Bruce to place him on the transfer list. Cissé eventually got himself back into the first team picture, but his relationship with Bruce continued to sour. After Christmas, Cissé only played three more games that season. At the end of the season, he signed for Portsmouth for £300,000 on a two-year contract, despite a strong transfer link to Premiership rivals Bolton Wanderers. The transfer was ultimately one of several included in the Stevens report released in June 2007, which expressed concerns of corruption within English football. Regarding Cissé, the report stated: "Agent Willie McKay acted for Portsmouth in the transfer of Cissé and [...] the inquiry is not prepared to clear these transfers at this stage".

After two years at Portsmouth, Cissé returned to Sedan in November 2006, after undergoing a two-week trial. He then signed for French Ligue 2 side Nîmes from Sedan in September 2008. Cissé played seven games during the 2008–09 season, before retiring from club football at the age of 33.

Cissé captained the Senegal national team at the 2002 FIFA World Cup. After a 1–0 victory over reigning world champions France on matchday one, the team made it all the way to the quarter-finals where they lost 1–0 to Turkey. Cissé was also part of the Senegal team who were the runners-up in the 2002 African Cup of Nations, but was one of the players who missed a penalty during the shootout in the final as they lost to Cameroon.
