The 1963–64 1. Liga season was the 32nd 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. At this time, the clubs in the two higher divisions in Switzerland were beginning to employ professional or semi-professional players.
There were 39 teams competing in the 1. Liga 1963–64 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 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).
