US Monastirienne

Union Sportive Monastirienne (USM) was founded on 17 March 1923 with a credit balance of 5,395 Tunisian francs. Following World War II, the club saw a resurgence in interest and enthusiasm for football among the people of Monastir. This led to the club's roster expanding to over one hundred players, with half of them playing for the senior team and the other half competing in the junior categories. Despite this growth, the following years proved to be more difficult for the club.

Following Tunisia's independence, US Monastir underwent a significant turning point. On the field, the club did not win any titles in the Tunisian Cup or the league during this period. However, USM consistently bounced back; after several relegations, the team managed to return to the first division. It was during the 1961–1962 season that USM reached the national division for the first time, having previously spent two seasons in the third division (1957–1958 and 1958–1959) and one season (1959–1960) in the Honor Division.

The 1980s marked a significant turning point for US Monastir, as the club became semi-professional, enabling the team to remain in the national division for fourteen consecutive years. During this period, USM also reached the semi-finals of the Tunisian Cup but were defeated 1–0 by Club Africain in Monastir after extra time. With a record of eight wins, eight losses, and ten draws, USM secured a solid fifth-place finish.However, this stability was short-lived.Since 1993–1994 season proved to be extremely challenging, particularly in terms of resources. Four coaches took charge in succession as the team struggled with numerous issues.

In July 2006, Néji Stambouli succeeded Zouhair Chaouch, who had served as president for six years.

On 3 May 2009, after a 3–2 victory against Espérance Sportive de Tunis at Stade El Menzah, USM qualified for their first-ever Tunisian Cup final. The final, held on 24 May at the Hammadi Agrebi Stadium in Radès, saw USM face CS Sfaxien, with CS Sfaxien winning 1–0 in the presence of President Zine El Abidine Ben Ali.

In the following years, USM's league position fluctuated between fifth and tenth place, until 2017.

Following the appointment of coaches Skandar Kasri and Lassaad Dridi, the team delivered solid performances, finishing the 2017/2018 season in sixth place and the 2018/2019 season in seventh place.

At the start of the 2019 season, US Monastir signed a contract with coach Lassaad Chabbi. During the 2019–2020 season, the team secured third place in the national league, which qualified them for continental competition for the first time in their history—the 2020–21 CAF Confederation Cup ,then the 2022–23 CAF Champions League , 2022–23 CAF Confederation Cup , the 2024–25 CAF Champions League and the 2025–26 CAF Champions League.

In the Tunisian Cup, renamed the Habib Bourguiba Cup in honor of the 20th anniversary of his passing, USM won the competition for the first time in its history, defeating Espérance de Tunis 2–0 in the final, on 27 September 2020.

After Chabbi's resignation as head coach, Afouène Gharbi took over, leading the team to a tenth-place finish. The club then appointed Mourad Okbi, who led them to their second-ever title by winning the Tunisian Super Cup,on 18 September 2021.
