Mirandés' origins can be traced to the beginnings of the 20th century, with clubs such as
El Deportivo Mirandés (1917),
Sporting Club Mirandés (1919),
Deportivo SC (1919), and
Miranda Unión Club (1922) all being its predecessors. Club Deportivo was founded as such on 3 May 1927, playing its first game on 4 June in the
Saint John of the Mountain Festival, against Arabarra, winning 1–0 courtesy of a Fidel Angulo goal; the team's first president was Arturo García del Río, with the organization's initial capital consisting of 666 shares of 15
pesetas each. From 1944 to 1977, Mirandés competed in
Tercera División, with the exception of three seasons spent in the regional leagues. The club's debut in Tercera división took place on 24 September 1944, with a 2–2 draw against Vasconia from
San Sebastián. In
1977–78, Mirandés moved to the newly created
Segunda División B, lasting five years, twice unsuccessful in the promotion playoffs. On 28 December 1977, the team faced
Mario Kempes and
Valencia at home in the
Copa del Rey, losing 2–4; future
Real Madrid player and
La Liga manager
Miguel Ángel Portugal played with the team during this decade. In 1986, Mirandés was one of the founders of the
La Rioja Football Federation. Three years later, the club won its first major trophy, conquering the fourth level championship under 23-year-old manager
Juan Manuel Lillo. The team went on to fluctuate between divisions three and four in the following years, again experiencing the odd visit to the regional levels (two seasons).
21st century Mirandés returned to the third division in the
2008–09 campaign, following two seasons in which the club finished the
regular season top of the table only to fall short in the playoffs. In the decisive match, the team won against
Jerez Industrial 3–2 at home (4–2 on aggregate). In
2011–12, Mirandés started the league with a run of 833 minutes without conceding a goal, eventually losing its first match in the 18th game. In
the season's domestic cup, the club reached the semi-finals – becoming the first third-tier team to make it to that stage since
Figueres in the
2001–02 edition – after disposing of top level sides
Villarreal,
Racing Santander, and
Espanyol, falling to
Athletic Bilbao. At the end of that season, the team was promoted to
Segunda División for the first time ever, after defeating
Atlético Baleares in
the playoffs. In the 2012–13 season, they managed to remain in Segunda División by finishing 15th out of 22 teams. There was another credible cup run in
2015–16, Mirandés eliminating top-division opponents
Málaga and
Deportivo La Coruña before losing to
Sevilla in the quarter-finals. At the end of the
2016–17 season, Mirandés was relegated after spending five years in the second division. On 28 March 2019, Mirandés won
that season's
Copa Federación after beating
Cornellà in the final. In the 2018–19 season, the club finished 3rd in Segunda División B, Group 2 and again was promoted to the Segunda División in
the playoffs, coincidentally overcoming Atlético Baleares once more. On 5 February 2020, Mirandés beat Villarreal 4–2 to reach the semi-finals of the
2019–20 Copa del Rey, also defeating two other La Liga teams
Celta Vigo and Sevilla; their run was ended by eventual winners
Real Sociedad. The club subsequently became known for their signing policy, consisting mainly of young players on loan. Mirandés finished fourth in the
2024–25 season and reached the
promotion playoff final against
Real Oviedo. They secured a 1–0 victory at home but missed out on promotion to La Liga after a 3–1 defeat away in the second leg, which went into extra time. ==Season to season==
