Čezsoča (pronounced [tʃɛˈsoːtʃa]; Italian: Oltresonzia) is a settlement in the Municipality of Bovec in the Littoral region of Slovenia. It includes the hamlets of Gorenja Vas (Slovene: Gorenja vas), Dolenja Vas (Dolenja vas), Jablanica, Kršovec, and Na Glavi.

Čezsoča lies in the valley on the left bank of the Soča River. The terrain then rises up towards Mount Polovnik (1,480 m). East of the settlement is Humčič Hill (810 m), behind which rises Mount Javoršček (1,557 m). Oplenk Creek flows through the village between Gorenja Vas and Dolenja Vas, and Slatenik Creek flows below Humčič Hill. The mountains block direct sunlight from the village from mid-November to the end of February, making the winter in Čezsoča more severe than in neighboring Bovec. The broad river banks on the Soča and its proximity to the town of Bovec make Čezsoča popular with visitors.

The village was badly damaged during the First World War because it was located on the front line. During the Second World War, Partisan troops in the First Bovec Company assembled in a World War I bunker at Humčič Hill in 1942. On 8 November 1943 the village came under German aerial bombardment and several houses were burned.

The church in Čezsoča is dedicated to Saint Anthony the Great. It was badly damaged during the First World War and restored in a Romanesque style in 1927. It contains the remnants of old frescoes. The altar painting is a 1931 work by Eda Galli.

In addition to Saint Anthony the Great Church, other sites in Čezsoča are registered as cultural heritage:
