Font-Romeu-Odeillo-Via (French pronunciation: [fɔ̃ ʁɔmø ɔdɛjo vja] ⓘ; Catalan: Font-romeu, Odelló i Vià), or simply Odeillo, is a commune in the Pyrénées-Orientales and Cerdagne near the Spanish border in the south of France.

Font-Romeu-Odeillo-Via station is served by the Yellow Train line, a railway which runs from Villefranche-de-Conflent to Latour-de-Carol.

[4] On 15 July 1035, Wifred II, Count of Cerdanya, gave Odeillo to the Abbey of Saint-Martin-du-Canigou, where he retired himself a short time before his death.

The Abbey of Saint-Michel-de-Cuxa also owned a few allods in Odeillo, as recognized by a papal bull from Sergius IV in 1011.

[5] In 1881, a wildfire caused by arson spread throughout 267 hectares of the forest of La Calme in the north of the commune.
