Lauwil is a municipality in the Waldenburg district of the Basel-Landschaft canton in Switzerland, first mentioned in 1194. During the Middle Ages, it was part of the Waldenburg lordship and had connections to the Ramstein family and the Schönthal monastery. Archaeological excavations in 1949 revealed remnants of the medieval St. Romai church, which likely served the local parish. The church was destroyed by fire in 1536 and rebuilt in 1562, while Lauwil has been linked to Bretzwil for church matters since 1765.

Photovoltaics contributed 252.13 MWh, and thermal solar energy added 24.58 MWh. The municipality's electricity consumption per capita was 3.4 MWh, ranking 48th among all municipalities.
