Downhill Strand (better known as Benone Strand) is a beach in County Londonderry, Northern Ireland. At 7 miles (11 km) long it is one of the longest in Northern Ireland, and recipient of the European Blue Flag and Seaside Award.

Downhill Strand beach forms the eastern end of a magnificent 7 mile (11km) stretch of sand and surf centred on the town of Castlerock. The beach at Downhill runs from just west of Castlerock to Magilligan Point. This is some of the most scenic coastline in Northern Ireland and there are fantastic views along the cliffs that back the beach.

Downhill Strand runs along the coast between Benone Strand and the cliffs immediately beneath Mussenden Temple. Downhill Burn flows from the hills above Downhill, flowing through the village of Downhill and crossing under the main road and under the railway, flowing on across Downhill Strand and emptying directly into the Atlantic Ocean.
