Officially Platense Sport Club was founded on July 4, 1960, in the neighborhood of Campo Rojo, Puerto Cortés. At first, Roger Riera, Roberto Mejía and Roosevelt Garbut attended at the home of Mr. Rene Paiz to found a new football team. They were joined by Manuel Flores, Héctor Sánchez, Rolando Méndez, Samuel Williams, Rudolph Williams, Ricardo Fúnez, Julio Linares, Óscar Pineda, Raúl Betancourt, Francisco Maldonado, Humberto Dole, Rolando Zavala and Reginaldo Guevara.
In the first meetings of Club Platense, the names of various international football clubs were included among the choices, from which the official name of the team was taken. Among the choices available were: Leyland, Banfield, Magallanes, and Platense of Argentina; the last was the most liked among the founder members of the club.
In its beginnings, this team had the fortune to have the support of the Tela Railroad Company. The members of Club Platense were, for the most part, hired by this company while they participated with the club. This benefited them a great deal, because in addition to their salary with Tela Railroad Co., where they received a special treatment for being soccer stars, they also received a salary from the ticket sales, as part of their contracts. That motivated these players to give 100% in training as well as in the official games.
After the Honduran National Soccer League was founded in 1964; Club Deportivo Platense became one of its 10 Original Club Members.
By 1965, Club Deportivo Platense already possessed the great and only honor, of being the first champion of the Honduran National Football League. Among the members of the famous team, that won the first championship, were: Gilberto Zavala, Tomas Maximo, Ricardo 'Cañon' Fúnez, Felix 'Mantequilla' Guerra, Raúl Betancourt, Santos 'Kubala' Díaz, Miguel 'El Chino' Hernandez, 'Pichingo' Crosdaile, Francisco Brocatto, Carlos "Care" Alvarado, "Chita" Arzú, León Victor "Escalera" Jallú, among others.
After having obtained the first championship of National League, Club Deportivo Platense had to wait 36 years until 2000-2001 for its second. The new format of short tournaments (opening – closure) with semifinals allowed Platense to compete for the championship, even though it finished second in the final standings. The title was to be fought in a series of two games against the most popular team of the country, Club Deportivo Olimpia. The first game was in Puerto Cortés and finished with a victory for the 'Tiburón' by the score of 1-0 with the goal netted by the Argentine Marcelo Verón. The return game was won by Club Olimpia by the same score. This forced the teams to go to over-time. The champion would be the team that scored the first goal (Golden goal). Then with a goal by Rony Morales, Club Platense conquered its second championship of the National League.
Relegation prevented and Platense F.C. formed
In June 2012, C.D. Platense was relegated but merged with C.D. Necaxa to become the newly named Platense F.C. and stay in the National League.
