The 1958–59 1. Liga season was the 27th 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 starting to employ semi-professional or even professional players.

There were 36 teams competing in the 1. Liga 1958–59 season. They were divided into three regional groups, each group with 12 teams. Within each group, the teams would play a double round-robin to decide their league position. Two points were awarded for a win and one point was awarded for a draw. The three group winners then contested a play-off round to decide the two promotion slots. The last placed team in each group were directly relegated to the 2. Liga (fourth tier). The three second last placed teams were to contest a play-out to decide the fourth relegation slot.
