The River Spey (Scottish Gaelic: Uisge Spè) is a river in the northeast of Scotland. It is the ninth longest river in the United Kingdom, as well as the third longest and fastest-flowing river in Scotland. It is important for salmon fishing and whisky production.

The origins of its name are unclear though 'hawthorn river' has been suggested (from a word linked to the Brythonic 'yspyddad') as has a derivation from the pre-Celtic 'squeas' meaning vomit or gush. Ptolemy named the river on his map of c. 150 as Tuesis. The name 'Spey' first appears in 1451.

The Spey is 107 miles (172 km) long. It rises at over 1,000 feet (300 m) at Loch Spey in Corrieyairack Forest in the Scottish Highlands, 10 miles (16 km) south of Fort Augustus. The river descends through Newtonmore and Kingussie, crossing Loch Insh before reaching Aviemore, giving its name to Strathspey. From there it flows the remaining 60 miles (97 km) north-east to the Moray Firth, reaching the sea 5 miles (8 km) west of Buckie.

On some sections of its course, the Spey changes course frequently, either gradually as a result of deposition and erosion from normal flow, or in a matter of hours as a result of spate. The Spey spates quickly due to its wide mountainous catchment area as a result of rainfall or snow-melt.

Insh Marshes, areas of roughly two miles (3 km) on either side of the Spey in the lower reaches are designated by Scottish Natural Heritage as a Site of Special Scientific Interest, as are the extensive shingle systems at Spey Bay.
