The Trelawny League was an English association football league comprising clubs from West Cornwall, formed from a merger between the Mining League and the Falmouth & Helston League at the end of the 2010–11 season. The new Trelawny League commenced in the 2011–12 season after the Falmouth and Helston League celebrated its 50th anniversary.[1]
The league originally consisted of seven divisions, but was reduced to six for the 2012–13 season, reduced to five for the 2016–17 season, and further reduced to four for the 2019–20 season after the creation of the St Piran League. The top division operated at the 13th tier of the English football league system. Up to two teams from the Premier Division could be promoted to the Cornwall Combination providing they finished in the top three and satisfied ground grading requirements.
Following the 2022–23 season, the league was absorbed into the St Piran League.
