The River Quoich is a tributary of the River Dee in Aberdeenshire, Scotland.^[1] It flows in a generally southerly direction and is about 15 km long (including its upper reaches, known as Quoich Water, above the confluence with the Allt an dubh-ghlinne). The clachan of Allanaquoich is situated just above the river's confluence with the Dee.^[1] Near Allanaquoich is the Linn of Quoich, a waterfall through a narrow ravine, over which there is a bridge at the narrowest part.^[1] Near the bridge is the Earl of Mar's Punch Bowl: a natural hole in a rock midstream that was literally used as a punchbowl after hunting deer in the neighbouring forest.^{[citation needed]} The river joins the Dee about 11⁄2 miles or 21⁄2 km west of Braemar.

The Linn of Quoich has been the site of several deaths in recent years, including those of an overworked, suicidal male doctor^[2] and a ten-year-old girl who fell into the river and drowned.^[3]
