Bojano or Boiano is a town and comune in the province of Campobasso, Molise, south-central Italy.

It was colonized under both the triumvirates, and by Vespasian, who settled veterans of Legio XI Claudia (whence the name Bovianum Undecumanorum, to distinguish it from Bovianum Vetus), and remained an important centre into late antiquity.

Paul the Deacon in his Historia Langobardorum writing after the year 787 says that in his time Bulgars still inhabited the area, and that even though they speak "Latin", "they have not forsaken the use of their own tongue".

After two centuries marked by Saracen attacks, in the mid-11th century Bojano was conquered by the Hauteville Normans, becoming a fief of Raoul de Moulins, a companion to Robert Guiscard.
