Viver i Serrateix (Catalan pronunciation: [biˈβej sərəˈteʃ]) is a municipality in the comarca of Berguedà, Catalonia.

The barons retained possession of the municipality's lands until the 17th century, when they sold it to the Rajadell family.

Soon thereafter, the towns of Mondarn and Pujol de Planes were also added to the united municipality.

The current parochial church of the municipality is what was formerly the Monastery of Santa Maria de Serrateix.

The present building, however, dates from the 17th century, and is principally in the Renaissance style, with late Gothic influences.
