This top division is a direct feeder to the Devon League South & West.

It is thus one of the few leagues in England to administer both Saturday and Sunday competitions.

Since 1904 a youth league, the Devon Junior and Minor League,[1] has existed as a platform for teams with age ranges of U9s to U18s in Plymouth, South West Devon and East Cornwall.

1 The 2019–20 season was abandoned by the league's executive committee due to the coronavirus pandemic.

The teams listed here were in first place in the standings at the time of abandonment, but were not officially recognised as champions.
