Streatley is a village and civil parish on the River Thames in Berkshire, England. The village faces Goring-on-Thames. The two places share in their shops, services, leisure, sports and much of their transport. Across the river is Goring & Streatley railway station and the village cluster adjoins a lock and weir. The west of the village is a mixture of agriculture and woodland plus a golf course. The village has a riverside hotel. Much of Streatley is at steeply varying elevations, ranging from 51m AOD to 185m at Streatley Warren, a hilltop point on its western border forming the eastern end of the Berkshire Downs. This Area of Outstanding Natural Beauty is topped by the 87-mile The Ridgeway path, which crosses the Thames at Goring and Streatley Bridge.

The River Thames, known alternatively in parts as the River Isis, is a river that flows through southern England including London. At 215 miles (346 km), it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn.
