The Sint-Pieterskerk is a church building in Lauw in the Belgian municipality of Tongeren in the province of Limburg. The church is located on the Lauwstraat, the main street through the village. About 50 meters to the south, on the other side of the street, is the higher walled cemetery.
The neo-Gothic building consists of a protruding west tower with three sections and a constricted needle spire, a basilical three-aisled nave with three bays, a transept with three-sided closure of both transept arms and a five-sided closed choir with a straight bay. The tower is equipped with superimposed buttresses and has a polygonal stair turret on the south side. On the north side of the tower is an octagonal baptistery and on the south side is a portal. In the west facade of the tower there is a pointed arch portal surmounted by a rose window, and there are also pointed arches in each facade. The central aisle is covered by a gable roof with slates and the two side aisles with pent roofs. The whole building is built in brick and finished with freestone and marl stone for corner blocks and decorative elements. The different parts of the building all have buttresses marking the bays and have pointed arch windows with tracery. The central nave also has pointed arched fanlights. The choir is lower, has a gable roof, is flanked by sacristies and on the north side is a polygonal stair turret. The transept arms have brick friezes below the cornices. Between the nave and the two aisles is a pointed arch arcade on beamed piers. Under the clerestory is a triforium. The vaulting of the building is done by rib vaults on pillars.
The church is the parish church of the village and dedicated to Saint Peter.
