Club Atlético Osasuna (Spanish pronunciation: [ˈkluβ aðˈletiko osaˈsuna], Athletic Club Osasuna), or simply Osasuna, is a Spanish football team based in Pamplona, in the autonomous community of Navarre.
Founded in 1920 it currently plays in La Liga, holding home games at the 19,800-capacity El Sadar Stadium. The team's home kit is red shirt, navy blue shorts, black socks with red back, whereas the away one is navy blue shirt, orange shorts and navy blue socks.
The word Osasuna means "health" in Basque (used in a sense of "strength", "vigour").
Founded in 1920, Osasuna first reached Segunda División in 1932. They made it to La Liga three seasons later.
The club achieved their first ever UEFA Cup qualification in 1985–86 after finishing sixth, eventually reaching the third round in the 1990–91 edition. Finishing last in 1993–94, the side spent six years in the second level; in 2005 it reached the Copa del Rey final for the first time ever, losing after extra time to Real Betis.
On the 27 November 2005, Osasuna played its 1,000th game in La Liga. After a stellar 2005–06 domestic campaign, Osasuna made history by finishing in fourth place – tied for best ever – synonymous with the chance of qualifying for the UEFA Champions League in the following season through play-off matches. This achievement was made even more dramatic by the suspense that was maintained until the last day of the championship in which Osasuna and Sevilla were both vying for the fourth place – both teams eventually ended the season with the same number of points but Osasuna got through due to their head-to-head record; However, Osasuna didn't make it to the Champions League group phase, as they were eliminated by Hamburg in the third qualifying round, leaving the Navarrese to vie in the UEFA Cup for the fifth time in their history.
