Friuli is bordered on the west by the Veneto region with the border running along the Livenza river, on the north by the crest of the Carnic Alps between Carnia and Austrian Carinthia, on the east by the Julian Alps, the border with Slovenia and the Timavo river, and on the south by the Adriatic Sea.
The adjacent Slovene parts of the Soča/Isonzo valley from Gorizia/Nova Gorica up to Mt. Triglav and the Vipava Valley, forming the Goriška region, may also be considered part of historic Friuli.

The mountainous northern part of the region belongs to the Southern Limestone Alps.
From west to east, the region's highest peaks are, in the Carnic Prealps (Dolomiti Friulane)—the Cima dei Preti, 2,703 metres (8,868 ft), Duranno 2,652 metres (8,701 ft), and Cridola 2,581 metres (8,468 ft); in the Carnic Alps—Peralba 2,694 metres (8,839 ft), Monte Bìvera 2,474 metres (8,117 ft) and Coglians 2,780 metres (9,120 ft); in the Julian Alps, the Jôf Fuârt 2,666 metres (8,747 ft), the Jôf di Montasio 2,754 metres (9,035 ft), Mangart 2,677 metres (8,783 ft), and Canin 2,587 metres (8,488 ft), which dominates the plain.

Rivers flowing southwards from the mountains are numerous.
The Friulian mountains surround the course of the Tagliamento river, which, at the latitude of Gemona del Friuli first crosses the hills that occupy the center of the Friuli, then flows into a large flood plain.
This plain is commonly divided into the High Friulian plain and the Low Friulian plain (Bassa Friulana), whose boundary is the Napoleonic road that connects the cities of Codroipo and Palmanova.
To the south of this road is the risorgive zone, where water resurfaces from underground waterways in spring-fed pools throughout the area.
South of the plains lie the lagoons of Marano and Grado, which are nature reserves.
Other important rivers include the Torre, Natisone, Stella, Isonzo/Soča, and Ausa.

Friuli covers an area of 8,240 square kilometres (3,180 sq mi), subdivided among the provinces of Udine 4,905 square kilometres (1,894 sq mi), Pordenone 2,178 square kilometres (841 sq mi) and Gorizia 466 square kilometres (180 sq mi).
The historical capital and most important city of is Udine, it was also the capital of the medieval Patria del Friuli.
