Neil Francis Lennon (born 25 June 1971) is a Northern Irish professional football manager and former player who currently manages Scottish Championship club Dunfermline Athletic.

During his playing career he represented English clubs Manchester City, Crewe Alexandra and Leicester City. Lennon moved to Celtic in 2000, where he made over 200 appearances and was appointed captain in 2005. Before retiring as a player, he returned to England and played for Nottingham Forest and Wycombe Wanderers. Lennon also earned 40 caps for the Northern Ireland national team over nine years, scoring two goals.

Lennon was appointed manager of former club Celtic in March 2010, initially in a caretaker capacity, following the departure of Tony Mowbray. Lennon enjoyed significant success as Celtic manager, winning three Scottish league championships, two Scottish Cups, qualifying for the group stage of the Champions League twice and the knockout stages once, before leaving the club in May 2014. After an unsuccessful spell back in England with Bolton Wanderers, marred by the club's financial problems, Lennon returned to Scottish football in 2016 with Hibernian. He led them to promotion back to the Scottish Premiership in his first season as head coach, and European qualification in his second season, before leaving Hibernian in January 2019.

Lennon returned to Celtic in February 2019, initially on an interim basis for the rest of the 2018–19 season, and guided them to the league and Scottish Cup titles. His contract was renewed and he led Celtic to the Scottish league title again in 2019–20. He also led the team to a fourth consecutive domestic treble by also winning the League Cup and the Scottish Cup that season. Lennon left Celtic in February 2021, as the club had fallen far behind Rangers in the 2020–21 Scottish Premiership.

Lennon returned to football a year later, becoming the new manager of Cypriot club Omonia in March 2022. Less than three months after arriving on the island, he led the club to win the Cypriot Cup, their first since 2012. He was sacked in October 2022 due to disappointing results in the domestic league.

Lennon was born in Lurgan, County Armagh, and attended St Michael's Grammar School in the town. As a youngster he played Gaelic football for the school and was also selected for the Armagh minor team. He grew up supporting Celtic and played football for the local Lurgan Celtic youth team.

Lennon joined Glenavon, after reaching the final of the Milk Cup with Glenavon Select and scored on his Irish League debut. He then joined Manchester City as a trainee in 1987. He made one first team appearance during his time in Manchester, a league match on 30 April 1988 away against Birmingham City, before signing for Crewe Alexandra on a free transfer in August 1990. Lennon made his debut for Crewe on 18 September 1990 against Reading. Despite missing the whole of season 1991–92 due to a back injury, he became an established member of the side and impressed with his intelligent play and consistent performances. Lennon's form saw him make his debut for Northern Ireland in 1994, and thus became the first Crewe Alexandra player in 60 years to win a full international cap. In 5+1⁄2 years at Crewe, Lennon made 187 appearances for the club and scored 18 goals.

In February 1996, Lennon signed for Leicester City for a fee of £750,000 (£1,800,000 today). In May 1996, Lennon played in the Leicester City side that defeated Crystal Palace 2–1 at Wembley in the Play-off Final to win promotion to the Premier League. On 16 April 1997, Lennon picked up his first major winner's medal when Leicester won 1–0 against Middlesbrough in a replayed League Cup Final. He played in a further two League Cup Finals during his time at Filbert Street, losing 1-0 to Tottenham Hotspur in March 1999 but winning 2–1 against Tranmere Rovers in February 2000.
