Cima di Jazzi, Mountain summit in Monte Rosa massif, Switzerland.

Cima di Jazzi is a rocky summit in the Monte Rosa massif that sits on the border between Italy and Switzerland. The peak shows steep walls and several climbing routes that pass through a high mountain landscape with snowfields and glaciers.

The summit has attracted climbers since the 19th century, when mountaineering routes were first established here. Improvements in climbing technique and gear over time opened new pathways to reach the peak.

The name Jazzi comes from a common Valais Alps term meaning "mountain pasture", although the summit itself is a snow cap above the glaciers. The Italian side rises above Macugnaga, whose alpine guides use the Rifugio Eugenio Sella and Bivacco Città di Luino as bases for routes on the east wall.

Rifugio Eugenio Sella provides a solid base for climbing trips at this elevation. Visitors should expect changing mountain conditions and rapidly shifting weather.

The name Jazzi comes from a common Valais alpine term meaning "mountain pasture", although the peak itself is a snow cap rising above the Weissgrats. Its east face drops about 1,800 metres over Macugnaga, and at its centre the Triangolo della Jazzi forms a 500-metre smooth rock wall first climbed on 28–29 June 1959 by the Bisaccia-Bertolini-Jachini rope team.
