The 2013–14 South West Peninsula League season was the seventh in the history of the South West Peninsula League, a football competition in England, that feeds the Premier Division of the Western Football League. The league had been formed in 2007 from the merger of the Devon County League and the South Western League, and is restricted to clubs based in Cornwall and Devon. The Premier Division of the South West Peninsula League is on the same level of the National League System as the Western League Division One.
