Adanaspor U21

A club under the name of Adanaspor was first founded in 1932; it competed in the Adana Amateur League. Orhan Kemal (the pen name of internationally known novelist Mehmet Raşit Öğütçü) played for this iteration of the club.

However, the club that would become Adanaspor was founded on January 23, 1954 by Mehmet Şanlıtürk, Mustafa Bekbaş, Erol Erk, Ali Gedikbaş and Dr. Muzaffer Eraslan. The club's original colours were yellow and navy, and it competed in the amateur league until 1966, when Adanaspor merged with Akinspor and Torosspor in order to become a fully professional club. The "new" club was admitted into the 2. Lig (the Second Division of Turkish football) in its first season as a professional club. After the merge, the club colours were changed to orange and white.

Adanaspor competed in the 2. Lig until they earned promotion to the 1. Lig (Süper Lig) at the conclusion of the 1970–71 season [tr]. They spent thirteen straight years in the 1. Lig, from 1971–84, competing in the UEFA Cup three times, and the Balkans Cup once. Adanaspor won its first cup, the Gençlik ve Spor Bakanlığı Kupası [tr], in 1973. They defeated İzmir Denizgücü SK [tr] 2–0 in the final, with Behçet Arkun and Orhan Yalçınkaya scoring the goals.

At the end of the 1975–76 season [tr], Adanaspor finished fourth, their highest finish in the top-flight at the time. Not long after, they went on to better their record, finishing second in 1980–81 [tr]. Despite the apparent success and upward progression, Adanaspor's fortunes took a turn for the worse, and they were relegated for the first time in 1984. They earned promotion in 1988 after winning the 2. Lig, but due to financial troubles, the club could not keep up their level of performance, and were relegated back to the 2. Lig at the end of the 1990–91 season.

The club spent the next several years bouncing back and forth between leagues, then spiraled out of control in the mid-2000s, culminating in a declaration of bankruptcy in 2005. During this period, Adanaspor were relegated three times in a row, ending up in the 3. Lig (Fourth Division) in 2006.

However, after hitting "rock bottom," their fortunes changed. Adanaspor earned double promotions in 2006–07 and 2007–08, and became regulars in the 1. Lig (Second Division) for the next decade, narrowly missing out on promotion to the Süper Lig at the end of the 2009–10 season. In 2011–12, they were again provided a chance to return to the top level of Turkish football, after qualifying to the Promotion Play-offs with a 6th place finish. They defeated Çaykur Rizespor 4–1 on aggregate in the two-legged semifinal, but lost 3-2 to Kasımpaşa after extra time in the Play-off Final. Finally, on 24 April 2016, after 12 years in the lower leagues, Adanaspor guaranteed their place in the Süper Lig for the 2016-17 season after coming back from 0–2 deficit to defeat Gaziantep BB 3–2 away from home. Unfortunately, after one season in the Süper Lig, they were immediately relegated back to the First League, where they have competed since.
