Stodhart Tunnel is a tunnel on the Peak Forest Tramway at Chapel Milton, Derbyshire. Until May 2013, it was considered to be the earliest rail-related tunnel in the world, but is now believed to be pre-dated by Fritchley Tunnel on the Butterley Gangroad at Fritchley, also in Derbyshire. One portal was destroyed by a road re-alignment in 1949, but the other survives.
