It was formerly a team of nationwide importance. The team played their first season in the Norwegian top division in the 1957–58 season and finished in sixth place out of eight teams in group B. In the 1959–60 season they finished second in the Main League group B, reaching a bronze play-off match which they won 4–2 against Vålerengen. Since this was the first time a bronze play-off was held, Eik became the first bronze medalists in Norwegian football's top division. In the following 1960–61 season they won the Main League group B, reaching a gold playoff match which they lost to Fredrikstad. Well-known players were Arne Natland, Arne Høivik and Tore Halvorsen, all of whom were capped by Norway.
Eik were promoted to the Norwegian top flight in 1982, finished fifth in 1983, and were relegated in 1985. Among the profiles on this team were midfielder Geir "Bolla" Johansen and striker Nick Sandberg, both of whom played briefly on the international stage, as well as future Tottenham goalkeeper Erik Thorstvedt who left the club after the 1983 season.
In the 1990s the team was a mainstay in the 1. divisjon, the second tier. After the 1997 season it even contested a playoff to win promotion to the Tippeligaen, but did not win. The team was relegated after the 2000 1. divisjon season, and played in the 2001 2. divisjon.
On 10 October 2001, a new club was founded. FK Tønsberg was to be an umbrella team in the district, and was supported by 20 teams in the region. As Eik-Tønsberg was the best regional team, FK Tønsberg took their place in the league system from 2002 and Eik-Tønsberg started anew.
The men's football team currently plays in the 4. divisjon, the fifth tier of Norwegian football, and two tiers below FK Tønsberg. Eik-Tønsberg won their 3. divisjon group in both 2003, 2004 and 2005, but in each year it succumbed to other clubs in the promotion playoffs. In 2010 the club also contested the playoffs as the 2nd placed team, but was again defeated, and remained in the 3. divisjon. It was relegated to the 4. divisisjon after the 2012 season.
