Złoty Stok [ˈzwɔtɨ ˈstɔk] (Czech: Rychleby, German: Reichenstein, "Richstone") is a town in Ząbkowice Śląskie County, Lower Silesian Voivodeship, in south-western Poland.

In 1491, Duke Henry I of the Czech Podiebrad family granted the town the coat of arms, banner and the title of a "Free Mining City".

At the beginning of the 16th century the town, called Reichenstein (literally "Richstone") by the Germans and Rychleby by the Czechs, began to flourish thanks to the mining and working of gold.

About 30,000 Allied PoWs were force-marched westward across Poland, Czechoslovakia and Germany in appalling winter conditions, lasting about four months from January to April 1945.

There are a number of historical monuments in the town, including a museum of gold mining and metallurgy (Muzeum Górnictwa i Hutnictwa Złota w Złotym Stoku).
