NK Pomorac is a Croatianfootball club based in Kostrena, a suburb of Rijeka, a port city lying on the Adriatic Sea. Kostrena is known for its maritime tradition, which is reflected in the club's name, as the word "pomorac" means "mariner" or "seaman" in English.
Founded in 1921, NK Pomorac is one of the oldest football clubs in Croatia. They currently compete in Druga HNL, Croatian second division. Pomorac had finished the 2009–10 and the 2011–12 seasons in second place, but were declined promotion as they were unable to gain a licence required to compete in top level. From 2012, they have been acting as a farm team for the nearby Prva HNL club HNK Rijeka.
Since the independence of Croatia in 1992 NK Pomorac played in Croatian Third Football League until the 1995–96 season, when they were promoted to the Druga HNL. NK Pomorac played in Druga HNL from 1996–97 to 2000–01, when they were promoted to the Prva HNL, Croatian top tier. The club had two seasons in Prva HNL - 2001–02 and 2002–03. Arguably, the 2001–02 season was the most successful in the club's history, as they finished 7th in the league and managed to reach the semifinal of the Croatian Cup. Since 2003, NK Pomorac have played in Druga HNL, where they regularly performed well and finished among the top teams.
