Osogna is a former municipality^[2] in the district of Riviera in the canton of Ticino in Switzerland.

On 2 April 2017 the former municipalities of Osogna, Cresciano, Iragna and Lodrino merged into the new municipality of Riviera.

Osogna is first mentioned around 1210–58 as Usonia.^[3]

Roman graves have been found near the Nala creek.

During the Middle Ages Osogna was under the spiritual and secular power of Milan Cathedral. During the reign of the Visconti in the 14th century, Osogna, Claro and Cresciano were combined under the jurisdiction of a governor. The town rights were confirmed in 1400. Between 1573 and 1798 Osogna was the residence of the Riviera Vogts and the center of government for the valley. After 1798, it was the seat of the district government.^[3]

The parish church of SS Felino e Gratiniano was built before the 13th century and was renovated in 1979–84. The other churches in the municipality are the church of S. Pietà from the 16th century and S. Maria del Castello from the 18th century.^[3]
