The Venice–Udine railway is an Italian railway line connecting Venice, in Veneto, with Udine, in Friuli-Venezia Giulia. It follows the same route as state highway 13 (SS 13, "Pontebbana"). The railway infrastructure is managed by the Rete Ferroviaria Italiana, which classifies it as one of its primary lines. It has a maximum line speed of 150 km/h.

History
The section between Mestre and Udine was opened between 1851 and 1860.

The electrification of the Mestre–Udine section at 3000 volts DC was officially inaugurated in October 1960.

Standards
The line is a double-track line entirely electrified at 3000 volts DC. The major cities crossed, in addition to the two termini, are Treviso and Pordenone.
