Trebula Mutusca was an ancient city of the Sabines. It is located at Monteleone Sabino, a village about 3 km to the east of the Via Salaria.
Pliny mentions both Sabine cities named Trebula: Trebulani qui cognominantur Mutuscaei, et qui Suffenates. As this seems to have been much the more important of the two Trebula, it is probably that meant by Strabo, who mentions Trebula without any distinctive adjunct but in conjunction with Eretum. The Liber Coloniarumn also mentions a "Tribule", municipium which is probably the same place. Martial also alludes to Trebula as situated among cold and damp mountain valleys, but it is not certain to which he refers.
Virgil speaks of Mutusca as abounding in olives, which is still the case with the neighbourhood of Monteleone Sabino, and a village near it consequently bears the name of Oliveto.
