The 1973 British League season was the 39th season of the top tier of motorcycle speedway in the United Kingdom and the ninth season of the British League.

Summary

Glasgow Tigers relocated to become Coatbridge Tigers. The Reading Racers won their first title, ending the dominance of Belle Vue Aces who could only finish in sixth place. Swede Anders Michanek was in imperious form, going undefeated at Reading Stadium (which was in its final year as a venue). He finished with an 11.36 average ahead of the four time world champion Ivan Mauger on 11.29. In addition to Michanek the Reading team was boosted by high scoring from Norwegian Dag Lövaas and Australian Geoff Curtis. In a sensational finish to the 1973 Knockout Cup final Reading were beaten by Belle Vue in a run-off for the Cup after an aggregate draw over two legs. Reading's success had a sour note after the season had finished when Geoff Curtis returned to Australia for the Australian season and was killed in a race at the Sydney Showground in December.
