Ganarew (from Welsh: Genau'r Rhiw; 'Gana-rhiw', and 'Gan y rew') is a village and small civil parish in south Herefordshire, England near the River Wye and the border with Wales.

The name Gana-rhiw, now Ganarew, may derive from the Briton "gan", from genau, meaning "a mouth or opening of a pass"; "rhiw" is a Welsh word for "hill" or "slope".

[14] The house is of stone with a slate roof, the 20th century extensions including a two-storey block with a bay window and a gabled porch.

[15] The manor is the home of Sir Colin Sheperd, former Member of Parliament for Hereford[16] and is a Grade II listed building.

[18] The Church of St Swithin churchyard contains a standing stone cross, of stepped form, which is a scheduled historical monument.

Other ancient monuments are noted by English Heritage at Ganarew Cross,[20] and at Little Doward camp, the remains of an Iron Age hillfort.

In the late 18th century, the turnpike route to Ross in the area of Ganarew Hill was described as being in such bad condition that it was a travel danger.
