Athens Kallithea

The club was founded on 18 August 1966 from the merger of five local clubs: Esperos, Iraklis, AE Kallitheas, Kallithaikos, and Pyrsos.

In 1970, Kallithea's Grigoris Lambrakis Stadium, named after the Greek liberal politician and peace activist Grigoris Lambrakis, was opened to the public.

On 28 April 2002, Kallithea clinched their first-ever promotion to Greece's top division with a 0-1 win over Chalkidona FC at Neapoli Stadium on a goal by Theofanis Gekas.

The club's first win in the competition was a 3–2 upset of PAOK at Toumba Stadium, thanks to two goals from Gekas, on 14 September 2002.

After four seasons in the top flight, Kallithea were relegated in the 2005-06 season.

In August 2021, New York-born Greek-American Ted Philipakos, a former Chief Executive Officer and Chief Brand Officer at Venezia FC, led the takeover of Kallithea FC with his brother and former professional footballer Peter Philipakos and investor Andrew Barroway.

In the 2021-22 season, Kallithea finished second in Super League 2, seven points back of league winners Levadiakos for promotion to Super League 1, which was the club's most successful season since it last appeared in the top division in 2005–06.

In September 2022, the club rebranded as Athens Kallithea FC. The presentation of the club's rebranding was met with widespread acclaim in Greece and abroad, with London-based Versus calling it "one of the cleanest football rebrands ever."

In the 2022-23 season, AKFC missed out on promotion to Super League 1 by one point, finishing second in Super League 2 for the second consecutive season.

After two consecutive second-place finishes, AKFC were crowned 2023-24 Super League 2 South Group champions and was promoted to Super League Greece.
