The 1904–05 season was St Helens' tenth in the Northern Rugby Football Union, the 31st in the club's sporting history. A year after gaining promotion back to the first division, St Helens once again struggled, and finished second-bottom. St Helens also competed in the end-of-season South West Lancashire mini-league, but could only finish fourth out of six. In the Challenge Cup, St Helens were beaten in the second round by Broughton Red Rose.
