Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the village was occupied and annexed by the USSR until 1941, then occupied by Germany until 1944, and re-occupied by the Soviet Union, which annexed it from Poland in 1945. During the Soviet times, Deliatyn was famous by the Kovpak's Oak, which symbolizes the uncompromised hatred of Ukrainians towards Nazi Germany.

On January 17, 1940, Deliatyn Raion [uk] was separated from Nadwórna County [uk]. In 1940 it received the status of an urban-type settlement, and on November 13, 1940, Deliatyn Raion was liquidated and entered the Yaremcha Raion [uk]. From December 30, 1962, it was part of the Bohorodchany Raion, but Deliatyn was assigned to the Nadvirna Raion.

Delatyn was home to a Jewish community until autumn 1941. German archives record mass executions of Jews in the town, carried out by an Einsatzgruppen.

[Lemberg Mosaic, Jakob Weiss, Alderbrook Press (2010)] Later, around 200 Jews were killed in the cemetery. During spring 1942, 3,000 Jews were shot. The remaining 2,000 Jews were deported from Deliatyn to the Bełżec extermination camp at the end of 1942.
