Nogometni Klub Široki Brijeg (English: Football Club Široki Brijeg) is a Croatian professional football club based in Široki Brijeg, Bosnia and Herzegovina that currently plays in the Premier League of Bosnia and Herzegovina. Considering the size of the town, NK Široki Brijeg has had a great deal of success and has started to expand that success to European Cups as well in recent years as is demonstrated by the club being a regular competitor in European Cups for the past 8 years.
The club was established in spring 1948, but due to many circumstances, some of them including unfavourable conditions towards the town of Široki Brijeg during the communist rule and relative size of it then, NK Široki Brijeg has experienced its greatest successes in the 1990s and onwards, and has become one of the most successful and organized clubs in Bosnia and Herzegovina today. They play on Pecara Stadium, a modern stadium with a capacity of about 8,000. The stadium itself meets all UEFA criteria. The club also has a fully equipped sports and recreational center just outside of town which is used as training grounds for the team.
