Leonard Victor Smith (9 February 1912 – 23 July 1967) was an Australian rules footballer who played for the Melbourne Football Club and Fitzroy Football Club in the Victorian Football League (VFL). The older brother of champion full-forward and coach Norm Smith, Len Smith was considered one of the pioneers of modern Australian rules football. Although his actual coaching career was short-lived due to struggles with ill health, his emphasis on speed, constructive handpassing and play-on had particular influence on Ron Barassi and Tom Hafey.
