The Králický Sněžník Mountains or Śnieżnik Mountains (Polish: Masyw Śnieżnika, Czech: Králický Sněžník, German: Glatzer Schneegebirge) is a massif and mountain range in the Eastern Sudetes on the border of the Czech Republic and Poland.

The Králický Sněžník Mountains is a mesoregion of the Eastern Sudetes within the Sudetes in the Bohemian Massif. All the highest mountains are located close to the Czech–Polish border or on the Czech side. The largest mountains are:

• Králický Sněžník, 1,423 m (4,669 ft)
• Mały Śnieżnik, 1,327 m (4,354 ft)
• Sušina, 1,321 m (4,334 ft)
• Hraniční skály, 1,320 m (4,330 ft)
• Podbělka, 1,308 m (4,291 ft)
• Černá kupa, 1,295 m (4,249 ft)

• Uhlisko, 1,241 m (4,072 ft)
• Slamník, 1,232 m (4,042 ft)

The territory has an area of 276 square kilometres (107 sq mi), of which 200 km (77 sq mi) in Poland and 76 km (29 sq mi) in the Czech Republic.

Three main European watersheds pass through the Králický Sněžník Mountains and they meet at Klepáč mountain (1145 m). Králický Sněžník forms an important hydrographic node, its territory belongs to three seas – the Black, North and Baltic Seas. The Morava River, which originates below the peak of Králický Sněžník, drains its waters into the Black Sea. The stream Lipkovský potok with its tributaries flows into the North Sea. The waters of the Eastern Neisse and its tributaries flow into the Baltic Sea.

Due to the terrain, there are no significant settlements here.

The territory of the massif is mainly formed by metamorphosed rocks – gneiss and schist, also marble.

On the Polish side the mountain range is largely covered by the protected area called Śnieżnik Landscape Park. On the Czech side, an area of 17.08 km (6.59 sq mi) is protected as a national nature reserve.
