Peillon (French pronunciation: [pɛjɔ̃]; Occitan: Pelhon; Italian: Peglione, formerly) is a rural commune in the Alpes-Maritimes department in the southeastern Provence-Alpes-Côte d'Azur region in France.

The village of Peillon, perched on a hilltop in the Paillon Valley, is known to have stairs instead of roads; it is dominated by its Église Saint-Sauveur (Saint Sauveur church), which was last restored in 1980.

It is also home to the Chapelle Notre-Dame des Sept Douleurs (Notre Dame des Sept Douleurs chapel), which features 15th-century fresco paintings by Giovanni Canavesio.

[3] The commune is served by Peillon-Sainte-Thècle station in the valley, on the Nice to Breil-sur-Roya SNCF railway.

In French, the inhabitants are called Peillonnais (masculine) and Peillonnaises (feminine).
