Yehoshua Sagi (Hebrew: יהושע שגיא; 27 September 1933 – 18 February 2021) was an Israeli intelligence officer and politician.

During the Suez Crisis in 1956, he served as intelligence officer of the Armored Corps and as commander of a reconnaissance unit.

Sagi opposed Operation Opera, the 1981 Israeli attack on the Iraqi Osirak nuclear reactor, saying "I do not believe fears of a 'Second Holocaust' justify the Israeli military taking any steps it thinks fit".

The result was the admission by U.S. Secretary of State Alexander Haig that the infiltration of terrorists over any of Israel's borders constituted a violation of the July 1981 ceasefire, but not terrorist actions against Israeli or Jewish targets outside of the region.

[2][3] Sagi was asked to resign in 1983 following the recommendations of the Kahan Commission, which had determined that he was guilty of indifference during massacres at Palestinian refugee camps in Israeli-occupied Lebanon.
