The 1973 British League Division Two season was the second tier of motorcycle speedway in Great Britain.

Summary

The 1973 season saw the league expanded to 18 teams with the addition of Chesterton Potters. The team had last raced during the 1963 Provincial Speedway League season under the name of the Stoke Potters. Boston Barracudas won their first title and went on to win the league and cup double. Boston had finished runner-up to Crewe Kings the previous season, with decent season averages recorded by five riders Arthur Price, Jim Ryman, Carl Glover, Russ Osborne and Ray Bales. With a largely unchanged team, they went one place better by sealing the league title. Boston won easily, 14 points clear of their nearest rival, and four of the five riders improved their averages from 1972. Arthur Price also won the Riders' Championship.
