The following is the summary of the Swiss National League in the 1963–64 football season, both Nationalliga A and Nationalliga B. This was the 67th season of top-tier and the 66th season of second-tier football in Switzerland.
Overview
The Swiss Football Association (ASF/SFV) had 28 member clubs at this time and these were devided into two divisions of 14 teams each. The teams played a double round-robin to decide their table positions. Two points were awarded for a win and one point was awarded for a draw. The top tier (NLA) was contested by the top 12 teams from the previous 1962–63 season and the two newly promoted teams FC Schaffhausen and Cantonal Neuchâtel. The champions would qualify for the 1964–65 European Cup and the last two teams in the league table at the end of the season were to be relegated.
The second-tier (NLB) was contested by the two teams that had been relegated from the NLA at the end of the last season, Young Fellows and Lugano, the ten teams that had been in third to twelfth position last season and the two newly promoted teams Etoile Carouge and Solothurn. The top two teams at the end of the season would be promoted to the 1964–65 NLA and the two last placed teams would be relegated to the 1964–65 Swiss 1. Liga.[1]
