Albareto is a meteorite which in July 1766 fell near the frazione Albareto, of Modena, Emilia-Romagna, Italy. (This town is very often erroneously confused with Albareto in the province of Parma.)

Albareto is a transitional ordinary chondrite between the L and the LL group. It belongs to the petrologic type 4.

The fall of the Albareto's meteorite is documented in a document "Della caduta di un sasso dall'aria" of the natural philosopher Domenico Troili.^[2] Troili didn't realize the extraterrestrial origin of the object but provided with his treatise one of the first chronicles of the fall of a meteorite.

In addition to describing the phenomenon, Troili carefully examined and noted the meteorite grains of a mineral similar to brass, which he called "marchesita" and that for long was thought to be pyrite (FeS₂). In 1862 the German mineralogist Gustav Rose analyzed the composition of this mineral, and determined a different chemical formula: FeS. Rose called this new mineral Troilite in honor of Domenico Troili^[3]
