Paceco (Sicilian: Paceca) is a town and comune in Western Sicily, Italy, administratively part of the province of Trapani, located nearby the Trapani city area, a distance of 5 kilometres (3 mi).

Conceived in conformity with a meditated urban scheme, Paceco's installation is a mesh perfectly orthogonal with some rectangular isolated (ippodomea plan), very recurrent in the inhabited places of the 17th century.

Local sights include the Cathedral Church, consecrated to the SS.

Recently the Church has been entirely restored in order to make it regain the original beauty.

In addition, there are the churches of Porto Salvo, Santo Padre, and Santa Lucia.
