The 1946 Northern League was a season of speedway racing in the United Kingdom for Northern British teams in 1946. With a National League in place and no Southern counterpart, it was effectively a second tier.[1]
Four of the six entrants were previously members of National League Division Two before war broke out. Glasgow and Birmingham were new entrants.[2]
Middlesbrough Bears won their first trophy.[3] The Bears only lost four league fixtures and had three riders in the leading averages; Frank Hodgson, Fred Curtis and Will Plant all contributed significantly during the season.[4]
During a fixture on 7 October at Brough Park the Birmingham Brummies Canadian rider Charlie Appleby crashed. A rider had fallen in front and in an effort to avoid the fallen rider, Appleby swerved and hit the machine instead. He was thrown into the air and suffered a fractured skull. He was taken to Newcastle Infirmary but died during the early hours of 8 October.[5]

On account of the small number of teams in the league the ACU Cup was run in a league format. Norwich Stars came out on top on points difference.
