The 1964–65 1. Liga season was the 33rd season of the 1. Liga since its creation in 1931. At this time, the 1. Liga was the third-tier of the Swiss football league system and it was the highest level of total amateur football. The two higher divisions in Switzerland, at this time, were becoming professional or semi-professional.
Format
There were 39 teams competing in the 1. Liga 1965–66 season. They were divided into three regional groups, each group with 13 teams. Within each group, the teams would play a double round-robin to decide their league position. Two points were awarded for a win. The three group winners and the three runners-up then contested a play-off round to decide the two promotion slots. The last two placed teams in each group were relegated to the 2. Liga (fourth tier).
Source: RSSSF Rules for classification: 1) Points; 2) Goal difference within the league, but decider play-off for qualifiers.
Promotion play-off
The three group winners and the runners-up played a round-robin against the four teams who had not been in their group. The teams did not play against the team that had been in the same group.
