The club was founded on 24 May 1925. It has carried the names
Ustrem,
Gotse Delchev,
Yane Sandanski and
Cherveno zname throughout its history. In 1977, Vihren first promoted to the B Group, remaining there 13 consecutive seasons before falling back to the V Group. In 1993, Vihren returned to the B Group, but only for one season, after which relegation again followed. In 2003, Vihren again returned to the second level. In the
2004–05 season, Vihren finished first and gained promotion to the
A Group for the
2005–06 season, marking the team's debut in the top tier. Before their first year of playing in A PFG, Vihren's owner decided to bring players from other countries to bolster the team's chances of surviving in the top flight. His first signing was the ex-
FC Porto player
Jose Furtado. He was from the Portuguese side
G.D. Tourizense for free. Brazilian player Serginio Dias, and Portuguese players Mauro Alexandre and Nuno Almeida were just a few other players who signed for Vihren after Furtado. The team coach was named
Petar Zhekov. Vihren finished season 2005–06 on 9th place in
A PFG with 30 points. The next season,
2006-07, Vihren managed to gain 37 points, finishing in 9th place once again. In season
2007–08, Vihren's owner, Konstantin Dinev decided to bring Portuguese coach Rui Dias. The club signed eight Portuguese and two Brazilian players. But three months later, Rui Dias was discharged for poor results. At the end of the season, the team finished in 10th place. Season
2008–09 started excellent with a 1–0 win against Bulgarian vice-champion
Levski Sofia. In the 4th round, the club defeated
Lokomotov Sofia. In January 2008, Vihren signed notable Greek players
Christos Maladenis and
Dimitrios Zografakis. In the end of the season, however, the team finished in 14th place and were relegated to
B Group, ending a four-year stint in the elite. The following two seasons were spent in the second tier, but financial problems overwhelmed the club, forcing its folding in 2011 and withdrawal from the B Group. The next season, Vihren was refounded from the fourth level, the A RFG. The team then promoted to the V Group in 2013. In 2025, Vihren promoted to the
Second League for the first time since 2011.
