Deportivo Alavés, S.A.D., usually abbreviated to Alavés, is a Spanish football club based in Vitoria-Gasteiz, in the Basque Country. Founded in 1921, it plays in Segunda División B, holding home matches at the 19,500-seater Estadio Mendizorrotza.

The team's home kit is blue and white-striped shirt, blue shorts and white socks.

Founded in 1921, Alavés first reached the first division eight years later, a stint which would last three years. After years of seriously facing disappearance, which went well into the 90s, the club finally achieved a second division promotion in 1994–95, after two consecutive years winning Segunda División B - created as the new third level in 1977 - but consistenly failing in the promotion playoffs.

In 1998–99, Alavés returned to the top level after a 42-year hiatus, achieving two wins against FC Barcelona in the following season, in which they would, for the first time, qualify for the UEFA Cup, ending the season sixth.

During that season, the Basque club reached the final of the UEFA Cup, a 4–5 loss against Liverpool (taking the game to extra time, and losing following an own golden goal), as well as finishing 10th in the domestic campaign.
