1964–65 in Belgian football

The Belgium national football team was drawn in the 1966 FIFA World Cup qualification group 1 with Israel and Bulgaria. Belgium won the first game against Israël, with the 3 other games being played during the 1965-66 season. For the first and only time in their history, Belgium started a game with all field players from the same club (RSC Anderlechtois) in the game against The Netherlands on September 30, 1964. Only the goalkeeper Guy Delhasse was from RFC Liégeois, but he was substituted at half time for Anderlecht keeper Jean-Marie Trappeniers. The manager of the national team was at the time Constant Vanden Stock, a former RSC Anderlechtois player and the future chairman of the club.

At the end of the season, RU Saint-Gilloise and KFC Diest were relegated to Division II and were replaced by R Racing White and RFC Malinois from Division II.
The bottom 2 clubs in Division II (KSC Eendracht Aalst and K Boom FC) were relegated to Division III, to be replaced by K Willebroekse SV and RFC Sérésien from Division III.
The bottom club of each Division III league (RRC de Gand, RFC Renaisien, Voorwaarts Tienen and R Uccle Sport) were relegated to the Promotion, to be replaced by RU Hutoise FC, K White Star Club Lauwe, KFC Brasschaat and RC de Jette from Promotion.
