The 1918–19 Northern Rugby Football Union season was the first season of rugby league football following a break during the Great War. The ban on competitive matches was removed in September 1918, but official games did not restart until January 1919. The season consisted of the Lancashire League and Yorkshire League, but the Championship did not restart until the 1919–20 season. Rochdale Hornets won the Lancashire League, and Hull F.C. won the Yorkshire League.

Season summary

Unofficial competition resumed in September 1918, but due to the increasing difficulties of raising a team, and further restrictions on travel, very few clubs had arranged fixtures. Following the end of the First World War, it was agreed to restart official competition in January 1919. Clubs competed in separate Lancashire and Yorkshire leagues.
