The Solis Viaduct (German: Soliser Viadukt) is a single track eleven-arched limestone railway viaduct. It spans the Albula east of the hamlet of Solis, in the canton of Graubünden, Switzerland.

Designed by the engineer Hans Studer, it was built in 1902 by Munari, Cayre und Marasi for the Rhaetian Railway, which still owns and uses it today. One of the most important structures on the World Heritage-listed Albula Railway, it is 89 metres (292 ft) high, 164 metres (538 ft) long, and has a main span of 42 metres (138 ft).
