Mornar Bar is a football club from the coastal Montenegrin town of Bar whose history dates back to December 1923. It was founded as JSK Crnojević, and during the following decades operated under the names Jadran, Obnova and Tempo. The club later adopted the name Mornar, under which it became established in Montenegrin football. One of the early milestones in its development came in 1950, when Mornar reached the Montenegrin Republic League.
For much of its history, Mornar competed outside the top level of Yugoslav and later Montenegrin football. In the Montenegrin Republic League, the club won three championships, in 1988/89, 1994/95 and 2000/01. The 1994/95 season was particularly successful, as Mornar also won the Montenegrin Republic Cup, completing a domestic double at republican level.
A major turning point in the modern history of the club came in 2009, when Mornar reached the Montenegrin First League for the first time. The club did not immediately establish itself permanently in the top division, however, and spent periods moving between the first and second tiers. In the 2020/21 season, Mornar won the second division and secured another promotion to the top flight.
The biggest breakthrough came in the 2023/24 season. Mornar finished second in the Montenegrin First League, behind only Budućnost Podgorica. It was the club's highest league finish since Montenegro became independent and also earned Mornar its first qualification for European competition.
The club's European debut produced one of the most memorable periods in its history. In the 2024/25 UEFA Conference League, Mornar first eliminated Dinamo Tbilisi. The Montenegrins won the opening match in Bar 2–1 before drawing 1–1 in Tbilisi, progressing 3–2 on aggregate.
In the second qualifying round, Mornar faced Serbian side Radnički 1923 Kragujevac. After losing the first leg 0–1, the Montenegrin club won the return match 2–1, forcing extra time and eventually prevailing 4–3 on penalties. Mornar therefore reached the third qualifying round of a European competition for the first time.
The third-round opponent was Hungarian club Paksi FC. Mornar lost the first leg 0–3 and drew the return 2–2. The 2–5 aggregate score ended the campaign, but six matches and a place in the third qualifying round remain the most significant European achievement in the club's history. UEFA records one win, three draws and two defeats from that campaign.
Another important chapter followed in 2025/26. Mornar again finished second in the league and then won the Montenegrin Cup, defeating Dečić Tuzi 1–0 in the final. The only goal was scored in the 67th minute by Stefan Denković, who struck spectacularly from around 30 metres. It was Mornar's first national cup since Montenegro regained independence and the club's first Montenegrin Cup triumph.
The cup victory gave Mornar another route into European competition. In the 2026/27 Conference League qualifiers, the club faced Andorran side Atlètic Club d'Escaldes. Mornar lost both matches 1–2 and was eliminated 2–4 on aggregate. It was nevertheless the second consecutive season in which the club took part in European qualifying.
Mornar's home ground is Stadion Topolica in Bar. The club is traditionally associated with blue and white colours, although some historical and database sources describe its colours differently.
The history of Mornar Bar is defined above all by its journey from a club that spent decades in regional football to a team capable of challenging for major honours in independent Montenegro. Three Montenegrin Republic League titles, two second-tier championships since 2006, two national league runner-up finishes and, most importantly, the 2025/26 Montenegrin Cup form the core of its domestic record. Its 2024 European campaign, which ended with a place in the third qualifying round of the Conference League, remains the club's greatest achievement on the international stage.
