The Chiesa di San Nicola di Silanis  (English: "Churc of San Nicola di Silanis") is a church in a state of ruins in the comune of Sedini, northern Sardinia, Italy.

History and description 
The church was built before 1122, when it is mentioned in a deed of donation in favor of the abbey of Montecassino, by the spouses Furatu de Gitil and Susanna de Zori, whose names appear carved on the facade of the church.
Its architecture, influenced by the Basilica of San Gavino in Porto Torres presents a synthesis between the First Romanesque and Pisan Romanesque ways: in particular there are several similarities with the cultural environment of Lucca at that time. 
This adhesion to that cultural model is also highlighted in the classical taste that emerges in the decorations of the capitals Corinthians on the facade and in the surviving column of the presbytery, and in particular in the pediment where, in the decorations of the frame, appear Egg-and-dart completely similar to those present in the canopy of the side portal of the church of Sant'Alessandro, Lucca.
