Knettishall Heath is an area of common land in Suffolk, England about 7 km east of Thetford near the Norfolk-Suffolk border. Popular with dog walkers and ramblers, it is the site where four long-distance footpaths meet: Angles Way, Icknield Way Path, Iceni Way and Peddars Way (part of the Peddars Way and Norfolk Coast Path National Trail).The Hereward Way ends at nearby Harling Road railway station in East Harling, linked to Knettishall Heath by path. The River Little Ouse flows through the heath.
