The municipality's name has its origins in several features of the town. It is named Sant Feliu after a primitive church erected atop a rock named the roca d'en Feliu, or "Felix's Rock". The main road through the municipality, which connected Prats de Lluçanès with Artés in Bages, followed the area's hilly natural contours along a ridge, hence Sasserra.
The municipality surrounds an exclave of Oristà.
Although the municipality lies within the natural region of Lluçanès, it voted in 2015 not to join a proposed new comarca of that name, but the plan was put on hold due to insufficient support.[3] In 2023 it briefly became incorporated into the new Lluçanès comarca,[4] [5] before the municipality voted to reunite with Bages.[6]
