The following is the summary of the Swiss National League in the 1971–72 football season, both Nationalliga A and Nationalliga B. This was the 75th season of top-tier and the 74th season of second-tier football in Switzerland.
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 season and the two newly promoted teams St. Gallen and FC Grenchen. This season's champions would qualify for the 1972–73 European Cup. The second and third placed teams were to be qualified for the 1972–73 UEFA Cup, but because second placed Zürich won the 1971–72 Swiss Cup, these UEFA rights were passed down to the third and fourth placed teams. The last two placed teams were to be relegated to the 1972–73 NLB.
The second-tier (NLB) was contested by the two teams that had been relegated from the NLA, Bellinzona and Fribourg, the teams that had been in third to twelfth position last season and the two newly promoted teams CS Chênois and AS Gambarogno. The top two teams at the end of the season would be promoted to the 1972–73 NLA and the last two teams would be relegated to the 1972–73 Swiss 1. Liga.[1]
The first round of the NLA was played on 14 August 1971. After playing 13 rounds, completed on 12 December, there was a winter break until the 14th round was held on 5 March 1972. The season had 26 rounds and was completed on 10 June 1972.
The decider was played on 13 June 1972 at the Hardturm in Zürich. St. Gallen won and remained in the top-level. Luzern were relegated to 1972–73 Nationalliga B.
