Vellescot (French pronunciation: [vɛlɛsko]) is a commune in the Territoire de Belfort department in Bourgogne-Franche-Comté in northeastern France.

Primarily agricultural, it is surrounded by forests and ponds whose formation is supported by the impermeable clay soil.

In the Gallo-Roman era, a minor road connecting Delle with Froidefontaine crossed Boron and Vellescot.

The village then formed part of the town hall and the parish of Grosne and returned in 1125 to Frederic, count of Ferrette.

Before the Second World War a metric gauge railroad of local interest ran between Belfort and Réchésy, which crossed Grosne, Vellescot and Suarce.
