Club Atlético Osasuna, the Pamplona-based football club founded on October 24, 1920, carries a crest deeply tied to Navarrese heraldry and the club’s founding colors of red and blue. The current badge, in use since a 2006 simplification, preserves the core elements that have defined the club’s visual identity for over a century: a royal crown, the initials C.A.O., and a central escutcheon featuring a crowned lion, all drawn from the historical symbols of Pamplona and the old Kingdom of Navarre.
Design and History
The first Osasuna emblem was an original design by Humbelino Urmeneta, dating to 1920, as confirmed by club founder Benjamín de Andoain on Radio Pamplona. That initial mark featured a triangle set against a vintage football background, topped by a crown representing the ancient Kingdom of Navarre. The triangle was split in two: red on the left, echoing the Navarrese flag and the club shirt, and blue on the right, a color combination attributed to a stained-glass window on the altar of Pamplona Cathedral. The letters C, A and O appeared in the corners, and the municipal ensign of Pamplona sat within the triangle.[1]
Before that first crest appeared in 1922, the club used an earlier seal as its initial institutional symbol. That seal, still used on official club documents, was later reproduced at heart level on Osasuna’s 2026/27 third kit as a tribute to the club’s founding at Café Kutz in Pamplona’s Plaza del Castillo.[2]
The crest evolved gradually. In 1928, the football background was removed and the triangle gave way to a shape closer to the modern badge, with the two halves replaced by a border also divided in two. The crown disappeared in 1931 with the proclamation of the Second Republic and returned in 1941, never to be removed again. During the 1950s, the Pamplona shield was reduced in size, the initials gained prominence and changed from white to gold, and the upper edge of the badge was rounded. In 1976, the Pamplona shield lost further visual weight and the “blue field” returned, with the border reverting to red. The border was widened in the 1980s, and in 2000 it was colored blue, a change that did not last.[1]
The current design dates from 2006, when the club simplified both colors and forms. Yellow was replaced with gold, the crown adopted a “monochrome” treatment with three small red details representing precious stones, and blue disappeared from the area corresponding to the Pamplona shield, which was reduced to a crowned lion and a border, both in gold. The C.A.O. initials and the red-and-blue palette were retained, and no further changes have been made since.[1]
Meaning and Symbolism
The crest’s heraldic language is explicitly regional. The crown at the top references the old Kingdom of Navarre, and the inner shield draws on the municipal arms of Pamplona, which feature a crowned lion. The club’s statutes describe the badge only as “the one currently registered in the Official Registry of Patents and Trademarks,” a definition that one club member has publicly criticized as too vague to prevent future unauthorized changes.[3]
That same member, José Mari Jaurrieta Zarranz, has argued that the lion in the current crest is heraldically incorrect. According to the Privilege of the Union, promulgated by Charles III of Navarre in 1423, the royal crown should appear above the lion’s back, not on its head, because Navarrese kings were crowned in Pamplona Cathedral. Jaurrieta notes that in the 1990s the crown did appear to one side on club kits, but it later returned to a position over the lion’s head, an error he says has been committed historically with the Pamplona shield itself across many representations in the city.[3]
The name “Osasuna” means “health, strength or vigor” in Basque, and the club’s red and blue colors have been constant throughout the badge’s evolution, appearing in every version from Urmeneta’s 1920 sketch to the present day.[1]
