Founded in 2014, it is the second reserve team of SD Eibar, and plays in Tercera Federación – Group 4, holding home matches in the Unbe Sports Complex.

Founded in 2014 as Urkomendi 14 Futbol Kirol (named after a local mountain), the club was created to accommodate young players who were released from SD Eibar.

[5][6] [7] Eibar Urko achieved a first-ever promotion to the fifth division in 2018,[8][9] and seemed set to advance further to the regional fourth tier (Tercera División) as 2019 champions of Gipuzkoa; however, Vitoria's relegation from the third level at the same time blocked Urko's promotion due to rules preventing teams owned by the same club competing in the same division.

[10] This also meant Urko could not be promoted at the end of the 2019–20 season either unless Vitoria achieved the same goal, but they were eliminated from the 2020 Tercera División play-offs.

[13] It occurred again two years later, but in 2023–24 the goal was achieved – Vitoria won their Tercera Federación group and Eibar Urko were Gipuzkoa champions again, both being promoted directly.
