The FC Basel 1945–46 season was the fifty-third season since the club's foundation on 15 November 1893. FC Basel played their home games in the Landhof in the district Wettstein in Kleinbasel. Emil Junker was the club's chairman. It was his second year as president of the club.
Max Barras was first team manager for the second season. Basel played a total of 42 games in their 1945–46 season. Of these 26 in the Nationalliga B, three in the Swiss Cup and 13 were test games. The test games resulted with seven victories, one draw and five defeats. In total, they won 28 games, drew six and lost eight times. In total, including the test games and the cup competition, they scored 141 goals and conceded 55.[1]
Basel had suffered relegation the previous season and their clear aim was to obtain immediate promotion. The Nationalliga B was contested by 14 teams. The two teams that finished at the top of the division were to be promoted and the two teams that finished in last and second last position in the league table would be relegated. Basel played a good season, winning 19 league matches, drawing five, losing only two matches. Thus they ended the season with 43 points in 1st position four points ahead of Urania Genève Sport in 2nd position and these two clubs won promotion.[2]
