Tignes (French pronunciation: [tiɲ]) is a commune in the Tarentaise Valley, in the Savoie department in the Rhône-Alpes region in south-eastern France, known for the highest skiable area and the longest ski season in Europe. It is located in the Savoie region with good transport links in and out of Lyon, Geneva and Chambéry.

It is best known as a snow sure ski resort. Together with neighbouring Val d'Isère, it forms the Tignes – Val d'Isère ski area. The proximity of two resorts offers one of the most seamless links between ski areas in Europe, in effect creating a single skiable area of over 300 km piste. Whilst not the largest ski area in the Alps, the level of integration between the two resorts is so good that it is often described as feeling like one of the largest single ski areas as a result.

Tignes was the freestyle skiing venue for the 1992 Winter Olympics, co-host city for the 1992 Winter Paralympics and host of the Winter X Games. This, coupled with the year round skiing, season length and large number of ski parks/slalom runs has cemented Tignes as the go to training ground for snow sport athletes.

The terrain of valley lends itself to more challenging skiing, with advanced skiers often opting for the resort as their preferred ski area. The town has however strived to improve its appeal to beginner and intermediate skiers with the introduction of easier runs lower down in the valley towards Tignes-Les-Brévières and upgrading existing chairlifts and installing new ones with smaller elevation gains.

The main villages of Tignes sit within a base of a high altitude valley with the Grande Motte at the furthest point and an array of other peaks wrapping around the valley. The other end is open, and drops away to the Lac du Chevril. This geography is described as having the feeling of being in a large open stadium, and Tignards (locals) often refer to the area as the "Stade Naturel", or Natural Stadium in English.

Tignes comprises 5 Villages; Tignes Val Claret, Tignes le Lac, Le Lavachet, Tignes Les Boisses and Tignes-les-Brévières. The first three are close together at 2100 m with Les Boisses and Les Brevieres further down the valley, above and below the dam respectively. All the towns located above the dam are linked by a free continuous shuttle bus. The only village located below these villages, Tignes Les Brévières, is accessible to the others via a free gondola service which operates late into the evening. Les Brévières remains the only remaining part of the original town, with all the others created as part of the dam construction or development of the ski resort. All the villages are part of the ski resort known as Tignes.

The original village of Tignes (at 1700m) was in the Isère valley below Val d'Isère. After the second world war, France needed electricity and it was decided to build the hydro-electric Tignes Dam in the Isère valley. Whilst this was a great achievement for French engineering and was for the greater good of France, it meant that the old village of Tignes was drowned. The dam was completed and the village was submerged in 1952. A replica of the original church was created in Tignes les Boisses. Once every 10 years the lake behind the dam (Lac du Chevril) is drained for maintenance work and the remains of the old village becomes visible.

The dam was painted with a fresco of Hercules in 1989 by Jean-Marie Pierret with the help of eight mountain climbers; it was funded by private corporations interested in boosting the Olympic appeal during the winter games of 1992 which took place in nearby Albertville.
