The Museo Etnografico Tiranese (MET) is an ethnographic museum in Tirano , a town in the valley of Valtellina in the Lombardy region (province of Sondrio). It was founded in 1973 thanks to the "Centro Iniziativa Giovanile (C.I.G.)" with the aim to document peasant life and culture of the mountain region of the Valtellina. The "Centro Iniziativa Giovanile" run the museum until the end of the year 2017, since then the municipality of Tirano took responsibility for the continuation and development of the museum.

The collection of the Museo Etnografico Tiranese is located since 1990 in the Casa del Penitenziere (Penitent's House), an 18th-century Palazzo nearby the Basilica Madonna di Tirano. Until then it was housed in the ground floor of the Palazzo San Michele, located as well at the square of the basilica. The collection was moved to its new location as a result of the Valtellina flood disaster of the summer of 1987.
