The 1992–93 Swiss 1. Liga was the 61st season of this league 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 amateur football.
There were 56 clubs in the 1. Liga, divided into four regional groups of 14 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 four group winners and the four runners-up then contested a play-off for the three promotion slots. The two last placed teams in each group were directly relegated to the 2. Liga (fourth tier). The four third-last placed teams would compete a play-out against the ninth relegation spot.
