CB Ciudad de Valladolid was founded in June 2015 by the former American-Spanish retired player Mike Hansen with the aim to replace CB Valladolid, the main club of the city, which was dissolved at the end of the 2014–15 season.

In its first season, in LEB Plata, Ciudad de Valladolid was relegated after finishing the league with only nine wins in 26 games. However, the club remained the league due to the existence of vacant spots.

As other teams in previous seasons, Ciudad de Valladolid took advantage and promoted to LEB Oro in the next season by defeating Fundación Lucentum, Morón and Zornotza in the promotion playoffs.

In 2020, when the team was leading the LEB Oro, the season was curtailed due to the COVID-19 pandemic. However, the club was awarded with the promotion to Liga ACB but did not fulfill the requirements for joining the league.

On 28 July 2020, Ciudad de Valladolid agreed collaboration terms with local association football club Real Valladolid and started to use their name, colors and crest.
