Moreton-in-Marsh is a market town in the Evenlode Valley, within the Cotswolds district and Area of Outstanding Natural Beauty in Gloucestershire, England. The town stands at the crossroads of the Fosse Way Roman road (now the A429) and the A44. It is served by Moreton-in-Marsh railway station on the Cotswold Line. It is relatively flat and low-lying compared with the surrounding Cotswold Hills. The River Evenlode rises near Batsford, runs around the edge of Moreton and meanders towards Oxford, where it flows into the Thames just east of Eynsham.
