Gryon (French pronunciation: [gʁijɔ̃] ⓘ) is a municipality of the canton of Vaud in Switzerland, located in the district of Aigle.

The entire village of Gryon and the Taveyanne area are designated as part of the Inventory of Swiss Heritage Sites.

[3] The municipality is located in the Aigle district, on a narrow terrace at an elevation of 1,110 m (3,640 ft) between the Gryonne and Avançon canyons.

The commune is composed of multiple settlements, which include the Gryon village, Barboleuse, Alpe des Chaux, Taveyanne, and Peuffeyre.

The lowest point is located at an altitude of 680 m at Peuffeyre next to the river Avançon d'Anzeinde.

After the old regime's fall, Gryon became part of the newly formed canton of Leman (1798-1803), which was consequently renamed Vaud after the Act of Mediation.

In 1798, the commune was attributed to the Aigle district, which remains part of today.

A motorable road was inaugurated in 1857, while the rack railway (Bex-Gryon-Villars-Chesières (BGVC)) opened in 1900.

In parallel, the poet Juste Olivier passed the later stages of his life in Gryon (1871-1876) where he wrote the famous song "Mi-été de Taveyeane", which was first sung in 1869.

In 1875, he published his work "Sentiers de Montagne", leaving a lasting mark on the history of Gryon through his contributions to the commune.

In the meantime, people from Lausanne and Geneva increasingly come to pass summer in Gryon.

In 1942, the two railway lines, BGVC and Villars-Bretaye fused to form a new train track Bex-Villars-Bretaye (BVB).

[6] In 1956, the gondola lift linking Gryon to les Chaux was realised, which was soon followed by a construction boom in the ski area.

The bridge over Gryonne (originally constructed in 1901) which provided a direct link with Villars-sur-Ollon was reconstructed in 1980.
