The Langhe (Italian pronunciation: [ˈlaŋɡe]; Langa is from old dialect Mons Langa et Bassa Langa) is a hilly area to the south and east of the river Tanaro in the province of Cuneo in Piedmont, northern Italy.

It is famous for its wines, cheeses, and truffles—particularly the white truffles of Alba. The countryside as it was in the first half of the 20th Century features prominently in the writings of Beppe Fenoglio and Cesare Pavese, who was born there, in Santo Stefano Belbo.
