AO Neas Ionias

At the end of the first decade of the previous century, the town of Nea Ionia had a lot of football clubs, each with its separate football history. The town was known to the rest of Athens for its sport-active inhabitants. Insights gleaned from the archives of the country's newspapers reveal intriguing details about a club named Omilos Filathlon Nea Ionia (OFNI), which is noted to have been established in either 1927 or 1928, according to different sources. The period from 1940 to 1942 saw the club halt its athletic programs as a result of World War II. Following the war, in 1947, the club re-emerged under the name AE Nea Ionia and began to systematically develop a variety of activities. In 1961, AE Eleftheroupoli assimilated the football club with the intention of forming a stronger team dedicated to excelling in the second division. The subsequent year witnessed the dissolution of the merger between the two clubs, primarily driven by numerous disagreements regarding the club's organizational structure. The year 1967 saw, once again, the club forced to merge with AE Eleftheroupoli, ultimately leading to the creation of Elpida Nea Ionia as a consequence of the junta regime's influence. Following the fall of the military junta in Greece, the club was reinstated and adopted the name AE Nea Ionia. The club Athlitiki Enosi Nea Ionia held onto its name until 1979, when it chose to rebrand itself as OFNI. In that same year, OFNI proceeded to merge with Ikaros football club and continued to operate under the name OFNI. In 1988, the newly established OFNI club underwent a merger with PAO Kalogreza, giving rise to Ionikos Nea Ionia. This partnership developed further when Ionikos allied with AO Neapoli, leading to the formation of AO Nea Ionia in 2001. The basic colours of the team are yellow and blue.

In the 2007–08 season, AEK Athens was scheduled to compete on artificial turf against Red Bull Salzburg in the second leg of the first qualifying round for the 2007–08 UEFA Cup. In a spirit of cooperation, Nea Ionia permitted AEK Athens to utilize its artificial pitch, facilitating the acclimatization of their players. In exchange, AEK Athens committed to competing in two friendly matches with the Ionian football club. The training center of AEK Athens and the Olympic Stadium of Athens hosted these friendly matches, both of which concluded with Nea Ionia football club suffering defeats (0-1 and 1-3).

The football club was relegated from the Greek Football League 2 in the 2014–15 season, as their performance resulted in a 13th-place standing in Group 4. The 2015–16 football season saw the club entering the local championships as a consequence of a change in ownership and serious financial issues.

In 2018, the club appealed to the Hellenic Football Federation for the training compensation (€29.500) of Marios Ogboe's transfer from OFI Crete to Hamilton Academical and won the case.

In April 2024, the football club of Nea Ionia won its first regional cup against Aris Petroupolis in a final held at Georgios Kamaras Stadium. In that same month, the club achieved a significant milestone by securing its inaugural regional championship.

On 11 September 2024, the football club of Nea Ionia defeated AER Afantou in the second qualifying round of the 2024–25 Greek Football Cup, recording its ninth win in the Greek Cup. On 15 September 2024, Nea Ionia defeated Anagennisi Artas breaking a record by advancing to the fourth qualifying round of the Greek Cup for the first time in its history. On 26 September 2024, the club was disqualified, in penalties (1-2), by Panionios football club and lost its chance to participate in the fifth round of the 2024–25 Greek Football Cup.
