The Cross Fidei et Virtuti, also referred to as Cross of Mentana, was a decoration for military merit bestowed by the Holy See during the Italian unification.

The cross was instituted by Pope Pius IX on 14 November 1867 after the victory of French-Papal troops in the Battle of Mentana.

Medal bars were attached to the ribbon to indicate the different battles that each individual cross was awarded for.
