Cave del Predil (German: Raibl, Slovene: Rabelj) is a frazione subdivision of the comune of Tarvisio in the Province of Udine, in the Friuli-Venezia Giulia region of northeastern Italy.

The hamlet is located about 15 km (9 mi) south of the Tarvis town centre, in the valley of the Rio del Lago (Seebachtal) between the Montasio and Mangart massifs of the Julian Alps.

A 4,844 m (15,892 ft) long tunnel under the pass, built in 1905 and originally used for water drainage and later for transport of miners and political refugees escaping from communist Yugoslavia, connects it with Log pod Mangartom.

The lead and zinc mining community was first mentioned in a 1320 deed issued by the Habsburg duke Frederick the Fair, at the time when the surrounding estates belonged to the Carinthian possessions held by the Prince-Bishopric of Bamberg.

The bishops also gained control over the trade route across the Nevea mountain pass leading to the city of Cividale del Friuli, the importance of which however diminished, after the Friulian lands in the south had been conquered by the Republic of Venice by 1420.
