FK Pirmasens is a German association football club in Pirmasens, Rhineland-Palatinate. The team was formed as the football section of the gymnastics and sports club TV Pirminia Pirmasens in 1903 and became independent in 1914. They took on their current name in 1925. FK is one of the few teams that uses the German Klub in their name as opposed to the commonly affected English-style term Club.
The club developed into a strong amateur side in southwestern Germany. In post-First World War play, the club was grouped in the tier-one Kreisliga Saar in 1919 but then moved to the Kreisliga Pfalz in 1920. From 1930 to 1933 the team made three consecutive appearances in the final of the Southern German championship, on the strength of four Bezirksliga Rhein-Saar titles, and between 1934 and 1936 were three times vice-champions of the Gauliga Südwest, one of sixteen top flight divisions formed in the re-organization of German football under the Third Reich. World War II was hard on the club: following a 0:26 beating at the hands of 1. FC Kaiserslautern in 1942 they withdrew from competition until after the conflict. After the war the club played in the Oberliga Südwest and captured league titles there in 1958, 1959 and 1960 while finishing as vice champions in 1954 and 1962. The club was so popular at the time that they often had to abandon their home ground in favour of the stadium in nearby Ludwigshafen in order to accommodate crowds of up to 65,000 spectators.
After the formation of the Bundesliga, Germany's new professional league, in 1963 Pirmasens found themselves in the second division Regionalliga Südwest where they consistently finished in the upper half of the league table over the course of the next decade. While they had several opportunities to advance to the Bundesliga through the promotion rounds they were unsuccessful. By the mid-70's the club was faltering. They narrowly missed relegation in 1977, only staying up because rival SV Völklingen was denied a license. However, by 1980 they found themselves in the Amateur Oberliga Südwest (III), slipped to the Verbandsliga Südwest by 1993, and just two seasons later were playing in the Landesliga Südwest (VI). The club has recovered nicely and climbed as high as the third division Regionalliga Süd in 2006-07.
In 2006, the club stunned German football when they defeated Werder Bremen in the first round of the DFB Cup in a penalty shootout.
Since 2007 the club plays in the Oberliga Südwest where the team has achieved good results, coming second in 2010 and 2011. From 2012-13 the Oberliga Südwest was renamed Oberliga Rheinland-Pfalz/Saar, with FKP continuing in this league. In 2014 the club won the championship in the league in 2014 and earned promotion to the Regionalliga Südwest.
