Morzine (French pronunciation: [mɔʁzin]; Arpitan: Morzena), alternatively known as Morzine-Avoriaz (pronounced [mɔʁzin avɔʁja]), is an alpine commune on the Swiss border in the Haute-Savoie department in the Auvergne-Rhône-Alpes region in Southeastern France.

It is located in the French-Swiss Chablais historical area, south-southeast of Évian-les-Bains and just west of Champéry in Valais. As of 2020, it had a population of 2,690. The town of Morzine is situated in the French Alps' Vallée d'Aulps (Aulps Valley), which stretches from Morzine to La Vernaz in the northwest.

A traditional market town in the heart of the Portes du Soleil, Morzine is dominated by chalets spread across a river gorge, bordered by partially wooded slopes which provide skiing even in poor weather conditions. Situated at an altitude of about 1,000 m, it is one of the most northerly of the French Alpine resorts, weatherwise benefiting from the Mont Blanc microclimate. The locality enjoys panoramic mountain views and modern ski facilities, as well as hotels and restaurants in the town itself. The ski resort of Avoriaz is located on the territory of the commune.
