The 2017–18 Liga FPD season, also known as Campeonato Banco Popular for sponsorship reasons, is the 97th since its establishment. The tournament is the first since the 2006–07 season to use the Apertura and Clausura names to their short tournaments, marking a departure from the Invierno and Verano tournaments. The Voit Lummo is the official match ball of the tournament. Herediano entered as the defending champions, but lost the title in the Apertura finals to Pérez Zeledón.
