The 1955 LeHi 300 (known officially in NASCAR as 1955-40) was a NASCAR Grand National Series event that was held on October 9, 1955, at Memphis-Arkansas Speedway in Lehi, Arkansas.

Drivers had to commute to the races, under their own power, using the same stock cars that competed in a typical weekend's race. This was due to a policy of homologation which ended around 1975. By 1980, NASCAR had stopped tracking the year model of the vehicles and most teams no longer took cars to the track under their own power.
