The first club was founded on 26 September 1963 under the name Mehanika. RK Metković has changed its name several times since his foundation, so it played under the names of Razvitak, Metković Jambo, and another team, Metković 1963, until reunification.
Accomplishments
In the 2000–01 season of the Croatian League, Metković and RK Zagreb tied for first place, but RK Zagreb had a home advantage in the finals, which were not completed. Metković finished first in the 2001–02 season of the Croatian League, but because of a player Blaženko Lacković whose transfer from RK Zagreb to Metković was not completed (it was still a case in arbitration; he played for them in a friendly match under a different name) they were moved to second place.
