The 2004–05 Swiss 1. Liga was the 73rd season of this league since its creation in 1931 and, at this time, it was the third tier of the Swiss football league system. The 1. Liga was also the highest level of Swiss amateur football, despite an ever-increasing number of clubs in this league playing with professional or, more often than not, semi-professional players in their ranks and this was not just the case with the U-21 teams of the professional clubs.
