The club is affiliated to Blekinge Fotbollförbund and plays its home games at Strandvallen. The club colours, reflected in their crest and kit, are yellow and black.

On 18 May 2023, Mjällby AIF played the Swedish Cup final at Strandvallen, losing 1–4 to BK Häcken.^[1] On 20 October 2025, Mjällby AIF secured its first Swedish Championship title with three games remaining in the 2025 Allsvenskan.^[2][3]

Mjällby Allmänna Idrottsförening was founded in 1939 in the small coastal community of Hällevik, in Sölvesborg Municipality, Blekinge County. The club was formed by a group of local football enthusiasts who wanted to create a permanent footballing presence in the area. In its early decades, Mjällby competed in the lower regional divisions of the Swedish football league system, establishing a modest but loyal local following. Throughout the 1940s and 1950s, the team played mainly at the amateur level, gradually building its infrastructure and reputation within Blekinge.

By the mid 1970s, Mjällby began to climb the divisions, becoming one of the more competitive clubs in southern Sweden outside of the major cities. A key moment came in the late 1970s when the club earned promotion to the second tier for the first time, marking the beginning of its rise toward national recognition. This period also saw the development of Strandvallen, the club’s home ground, into a more structured stadium capable of hosting larger crowds.

Mjällby reached the top flight, Allsvenskan, for the first time in 1980. Their debut season in the highest division was viewed as a major achievement for a club from such a small community. Although they were relegated after just one season, they returned several times throughout the 1980s and 1990s, often earning a reputation as a well-organized, resilient side. The club became known as one of Sweden’s classic “yo-yo clubs,” moving between Allsvenskan and the second tier, Superettan, but managing to maintain a stable identity and loyal support.

In the early 2000s, Mjällby established itself more consistently in the top two tiers of Swedish football. Promotion to Allsvenskan in 2009 marked the start of a more stable era, with the team achieving respectable mid-table finishes and building a solid foundation. Despite limited financial resources compared to the country’s larger clubs, Mjällby developed a reputation for strong youth development and scouting in the Blekinge region.

The 2025 season became the defining chapter in the club's history. Under coach Anders Torstensson, Mjällby won their first Allsvenskan title on 20 October 2025, securing the championship with three matches to play. The potential triumph and its subsequent success drew worldwide attention and was considered one of the most remarkable underdog stories in modern football, as its team was made up of mostly locally-born players in the nearby village of Hällevik—with a population of 800 inhabitants. For also the first time in their history, Mjällby qualified for European football, entering the 2026–27 UEFA Champions League second qualifying round.^[4][5][6] Afterwards, they ended the 2025 season with a record-breaking total of 75 points.^[7]

Mjällby's rivals can be divided into three categories. The first category includes the closest competitors geographically in Blekinge and northeastern Skåne. Historically, the most local rivals have been Sölvesborgs GoIF and Ifö Bromölla IF. Over a longer time and recently games against FK Karlskrona and Kristianstad FC have been described as derbies. Both of the clubs are rivals to Mjällby on a regional level. Games against FK Karlskrona are of importance as they involve the two best clubs in the province of Blekinge. And also a general rivalry, that also excludes sports between western and eastern part of the province. Where Mjällby represents the western part and Karlskrona the eastern part of Blekinge.

The third category, rivals in the south of Sweden who usually play in the Allsvenskan and Superettan (first and second tier). Especially games against Malmö FF are considered by many Mjällby fans and players to be the most prestigious. From the Malmö fans' perspective, the matches are not as important as they usually believe they have bigger competitors in Allsvenskan. In this category but with less prestige, in descending order these clubs can be included, Kalmar FF, Östers IF, Helsingborgs IF and Landskrona BoIS. In the latter category, contains clubs that plays in the same league level as Mjällby more frequently than the clubs in the first and second categories.

Strandvallen, a multi-use stadium in Hällevik, serves the home stadium of Mjällby AIF. The stadium holds 7,000 people^[8] and was built in 1953.^[9]
