Standedge (normally pronounced Stannige) is a moorland escarpment in the Pennine Hills of northern England. Located between Marsden and Diggle, on the edges of the metropolitan counties of West Yorkshire and Greater Manchester respectively, Standedge has been a major moorland crossing point since Roman times and possibly earlier.

From east to west, Standedge is crossed on the surface by no fewer than five generations of road crossing, the earliest being a Roman road from York to Chester, whilst the latest is the current A62. The Huddersfield Narrow Canal and the railway line from Leeds to Manchester both burrow below Standedge through the Standedge Tunnels. The Pennine Way long distance footpath also crosses Standedge, but in this case the path runs south to north along the Pennines.

Much of Standedge forms part of the National Trust's Marsden Moor Estate. From an administrative perspective, Standedge is split between the metropolitan boroughs of Kirklees and Oldham.

The earliest known crossing of Standedge is the Roman road connecting the Roman forts of Slack and Castleshaw, on the way from York to Chester. The road is believed to have been built in AD80. Its course was identified in 1969 to the north-east of Castleshaw fort, climbing Standedge Ridge by means of a graded terraceway. The road was originally more than 22 feet (6.7 m) wide but has been considerably eroded.
