The 1948 National League Division One was the 14th season of speedway in the United Kingdom and the third post-war season of the highest tier of motorcycle speedway in Great Britain.

Summary

The entrant list was the same as the previous season. New Cross Rangers won the National League for the second time.

Fatalities

1948 proved to be the worst season so far in regard to fatalities. During the 1947 season two riders had died on the same day but 1948 saw three riders killed during the season. It started with 37-year-old Reg Craven, on his debut for Yarmouth Bloaters. Craven crashed with two Poole Pirates riders at Poole (on 26 April) during a National Trophy match and died eight days later (4 May) from a fractured skull in hospital. Billy Wilson of Norwich Stars and Eric Dunn of Hastings Saxons from the lower divisions were also killed.
