The St Cuthbert Mayne Way is a Pilgrim Way from the Cathedral of SS Mary & Boniface in Plymouth to the Shrine of St Cuthbert Mayne in Launceston.

Cuthbert Mayne was an English Catholic priest executed in Launceston under the laws of Elizabeth I. Mayne was beatified in 1886 and canonised as one of the Forty Martyrs of England and Wales in 1970.

The Way leaves the Cathedral and crosses Victoria Park to reach the Church of the Most Holy Redeemer near Plymouth docks and then the Church of St Paul. The route leaves Plymouth and follows the Tamar Valley Discovery Trail. The River Tavy is crossed using a ford near Lopwell House to reach Bere Alston Station where a train must be taken to Calstock. The Way continues to follow the Tamar Valley Discovery Trail northwards over rolling hills and riverside meadows. After Horsebridge the route is mainly on quiet lanes to Milton Abbot. Finally the Way reaches Launceston and the Church and Shrine of St Cuthbert Mayne. 

NB the route involves two river crossings, one by a ford and one by short train ride.
