Lavaux (French pronunciation: [lavo]) is a region in the canton of Vaud in Switzerland, in the district of Lavaux-Oron.

Lavaux consists of 830 hectares of terraced vineyards that stretch for about 30 km along the south-facing northern shores of Lake Geneva.

It benefits from a temperate climate, but the southern aspect of the terraces with the reflection of the sun in the lake and the stone walls gives a mediterranean character to the region.

There is a hiking trail ("Terrasses de Lavaux"), going from Saint-Saphorin to Lutry, recommended by the Tourism Office of Switzerland.

The counter-initiative of the regional government (Council of State of Vaud) was accepted by 68% of voters (strengthening the protection but less strictly than the initiative of Franz Weber).
