Founded on 25 May 1905, Platense played in the second division from 1956 to 1964, and from 1972 to 1976, when the team finally won its first title, the
Primera B championship that allowed Platense to play in the
Primera División. The club achieved cult status in the late 1970s as they repeatedly staved off relegation through a series of "last-day miracles" (relegating other teams such as
Temperley after defeating them in decisive matches played to keep a place in the first division. Platense survived at the top level of Argentine football until finally succumbing to relegation in 1999. This would be the beginning of a steep decline: Platense was subsequently relegated to the regionalised third division,
Primera B Metropolitana, at the end of the 2001–02 season. On 17 May 2006, Platense won its second title and was promoted back to the Argentine second division
Nacional B. But on 8 May 2010
The Squid would be relegated again to the third category. On 2 May 2018, Platense was directly promoted to the second division after winning the Primera B Metropolitana title in a victory over club Estudiantes de Caseros. In 2021, Platense would make their return to the Primera División for the first time in 22 years after defeating
Estudiantes de Río Cuarto on penalties to earn promotion. In 2023, Platense reached the final of the league cup, defeating Godoy Cruz in a heart-stopping penalty shootout. After almost 20 penalties taken, right back Raul Lozano converted the final penalty, leading the team to play their first final in more than 80 years. Platense lost the final against Rosario Central, achieving a historic runner-up finish. The club's main claim to fame during these lean years is the success of Momo and
David Trezeguet, who had debuted at Platense but after playing only 5 matches in
Argentine Primera División was transferred to
AS Monaco. Platense's fans base can be found in Vicente López, Olivos and Florida towns (all of them part of the
Vicente López Partido), as well as in
Villa Urquiza and
Saavedra neighbourhoods. The club is also cited in
Bioy Casares's book
El Sueño de los héroes ("Dream of Heroes" ). Among its supporters, the
Tango music singer
Roberto Goyeneche and the British author Chris Moss were probably the most notable fans. On the 1st of June 2025,
Guido Mainero scored the only goal of the game as Platense defeated
Huracán 1-0 in the Apertura Final to become Primera División champions for the first time in the club's history. == Team image ==
