Seillans (French pronunciation: [sɛjɑ̃]; Occitan: Selhan) is a commune in the Var department in the Provence-Alpes-Côte d'Azur region in southeastern France.

It is a ville perché (perched hill-top village) overlooking the plain between the southern Alps and the Esterel, which borders the sea between Cannes and Saint-Raphaël.

It is the westernmost of a line of such towns and villages (including Montauroux, Callian, Tourrettes and Fayence) that face south and attract tourists.

Seillans is also a destination for holiday-makers, retirees and second-home owners from other parts of France and northern Europe.

Seillans has an annual pottery market and many concerts and events throughout the year, as well as the annual international Musique-Cordiale Festival, a fortnight when the church, the salle polyvalente and outdoor venues resound to a variety of high quality classical, choral and jazz music from international artists, soloists, choirs and orchestras each August, when the area is at its most popular.
