Torgnon (French: [tɔʁɲɔ̃] ⓘ; Valdôtain: Torgnòn; Issime Walser: Tornjunh) is a town and comune in the Aosta Valley region of north-western Italy.

One of the most prominent families from Torgnon was the Besenval family, whose descendants later acquired citizenship in Solothurn and, as Swiss nationals, pursued careers in French service. The best-known member was Pierre Victor, Baron de Besenval de Brunstatt, an officer in French service. At his Paris residence, the Hôtel de Besenval, the baron hosted leading figures of French society, including members of the royal family. Since 1938, the Hôtel de Besenval has housed the Embassy of the Swiss Confederation and the residence of the Swiss ambassador to France.
The main line of the family died out in 1927 with Amédée Victor Louis, Comte de Besenval (1862–1927), who lived in Naples.
