FK Jūrnieks was a Latvian football club based in Riga. It became defunct in 1997. In 2017, the club got reinstated in Latvia's division 2.
Most of football clubs in the Soviet Union were attached to factories and the footballers were officially factory workers. With Latvian league clubs it was partly true, as footballers usually did indeed work part-time in the factories.
The club most widely known as Jūrnieks was the football club of the Riga factory of ship building and repairing. In 1959 under the name KBRR the club made its début in the Riga championship, in 1962 it first played in the Latvian league where it got a respectable fifth-place finish, in 1963 it won the silver medals in the league, the following year the club's name was changed to KRR. Until 1967 the club finished in the upper half of the league every year. The clubs leaders in the early years were the goal-scoring forward Polukarovs, goalkeeper Kurbatovs and former Daugava Riga footballer Vladimirs Amosovs.
In 1968 the club was renamed to FK Jūrnieks, the name that it had in its most glorious years. In 1970 it won the Latvian Cup for the first time by beating VEF Rīga. In 1972 in addition to the second cup victory Jūrnieks also won its first (and only) Latvian league title. In those years the club was coached by M.Titarenko. The most notable footballers of Jūrnieks in the end of the 1960s – beginning of the 1970s were V.Liholajs, Uhanovs, G.Zvejnieks and Vladimirs Trusovs.
However, after 1972 Jūrnieks failed to remain one of the top football clubs in the Latvian league. Never again would it win medals of any sorts in the league, in the Latvian Cup it also never reached the finals again. From 1973 to 1991 it was a middle class team that hardly could compete with clubs like Torpedo Rīga, Elektrons Rīga, Enerģija Rīga, Ķīmiķis Daugavpils and VEF Rīga. The best finish was achieved in 1986 when Jūrnieks finished in the fourth place in the Latvian league. Un those later years the leading players with Jūrnieks were A.Skudra, goalkeepers Gordejevs, Zaicevs and Raitis Gultnieks and strikers Mihails Juropovs and Jaroslavs Petrovs. For several years with Jūrnieks also played Vjačeslavs Fanduļs, mostly known as ice hockey player who played with Dinamo Riga and with Latvia national ice hockey team.
