The 1918 Auckland Rugby League season was its 10th since its inception in 1909. It was again severely affected by the ongoing war with several hundred players serving overseas and 44 killed who were named in the annual report. North Shore Albions withdrew from the competition early in the season and on other occasions teams played short-handed. There was also a truncated representative program with only a trial match and one full Auckland representative match versus Canterbury, which was played at the Auckland Domain in front of 10,000 spectators.
