The Wiesen Viaduct is a single-track railway viaduct, made from concrete blocks with dimension stone coverage. It spans the Landwasser southwest of the hamlet of Wiesen, in the canton of Grisons, Switzerland.
Designed by the then chief engineer of the Rhaetian Railway, Henning Friedrich, it was built between 1906 and 1909 by the contractor G. Marasi under the supervision of P. Salaz and Hans Studer. The Rhaetian Railway still owns and uses it today for regular service. An important element of the Davos–Filisur railway, the viaduct is 88.9 metres high and 210 metres long; it has a main span of 55 metres.
