Kalloni (Greek: Καλλονή, before 1927: Λούντσι – Lountsi) is a village and a community of the Grevena municipality located within the administrative region of Western Macedonia in northern Greece. It is located some 29 kms northwest of Grevena.

The village is situated at about 980 m above sea level in the eastern foothills of the northernmost section of the Pindus Mountains. The village consists of some 70 odd buildings, built into a steep hillside. It is surrounded by dense oak forests punctuated by sandstone formations. The community of Kalloni covers an area of 9.447 km².

Kalloni is best known for the traditional stone architecture of its houses and public buildings which mostly date from the late nineteenth and early twentieth century. Kalloni forms part of the network of villages known as "the Mastorohoria" ("the stone masons' villages") which straddle the boundary of the Grevena and Voion municipalities. Kalloni, Pentalofos and Siatista are the only three settlements in these municipalities listed under the 1978 Presidential Decree for the architectural heritage protection of traditional settlements.
