The city of Alcoy had a very important club, the Boxing Club Deportivo Alcoyano. In 1927 its football section won a large number of games against major clubs which led to the formation of the football club.[5]Club Deportivo Alcoyano saw the light in 1928, after a merger between two clubs in the city, Levante and Racing. However, it only joined the Royal Spanish Football Federation four years later.
In 1942, the club first reached the Segunda División, going on to alternate between that level and the top flight in the subsequent years. Their debut in the latter took place with a 2–3 home loss against Real Murcia, in an eventual relegation, as second from bottom. In that season the club got only 8 points and conceded 28 goals in 14 games played, the worst result among 8 teams.[6] For the first time in history Alcoyano reached La Liga, first Spanish division, in 1945 by winning Segunda División.[7]
In 1947–48, Alcoyano maintained its first division status for the only time in its history, even finishing higher than Real Madrid. That season was the best in Alcoyano's history – the club finished in 10th position in La Liga.[7] The following forty years, however, were spent mainly in the third and fourth divisions, with very brief spells in level two. In the 1953–54 season Alcoyano was relegated to the Tercera División for the first time in its history.[7] In the 1954–55 season the club reached first place in the Group 10 of Tercera División, but failed to promote back to Segunda División B.[8]
Alcoyano returned to the third category for 2004–05, consistently reached the promotion play-offs, and consistently failed to be promoted. In the 2005–06 season, the team also had a good run in the Spanish Cup, beating RCD Mallorca 4–1 and losing by just one goal (0–1) in the fourth round against Atlético Madrid.
In June 2011, 42 years after, Alcoyano finally returned to the second division, after finishing in third position in the regular season, and disposing of Real Madrid Castilla, SD Eibar and CD Lugo in the promotion playoffs. However, the club spent only one season in the second division and relegated back to Segunda División B.[9] On 1 August 2014, the club completed the transformation process into "Public Limited Sports Company" (Sociedad Anónima Deportiva).[7]
In the 2018–19 season, Alcoyano club finished 16th in the Segunda División B, Group 3, close to the relegation place.[10]
On 20 January 2021, Alcoyano made history by eliminating Spanish giants and reigning La Liga champions Real Madrid from the 2020–21 Copa del Rey, beating them 2–1 at home.[11]
