Milecastle 49 (Harrows Scar) was a milecastle on Hadrian's Wall (grid reference NY6202866407).

Milecastle 49 is situated immediately west of the gorge of the River Irthing where the Wall was carried over the river by the bridge at Willowford. The scar or cliff and hence the milecastle are named after an ancient tenement called The Harrows which stood nearby. The tenement is shown on William Howard's 1603 map of the Barony of Gilsland and on an estate map of The Shaws commissioned by John Carrick around 1800.

Harrows Scar measures 19.8 metres east to west by 22.9 metres north to south and no contemporary internal buildings are now visible. It is built with narrow gauge defensive walls which are bonded with the Narrow Wall curtain of Hadrian's Wall on either side. It has Type III gateways. It lies 1458m west of Milecastle 48 and 1391m east of Milecastle 50.
