The Six-Day War also known as the June War, 1967 Arab–Israeli War, or Third Arab–Israeli War, was fought between June 5 and 10, 1967 by Israel and the neighbouring states of Egypt (known at the time as the United Arab Republic), Jordan, and Syria.

Relations between Israel and its neighbours had never fully normalised following the 1948 Arab–Israeli War. In the period leading up to June 1967, tensions became dangerously heightened. Israel reiterated its 1950s statement that the closure of the straits of Tiran to its shipping would be a casus belli and in late May Nasser announced the straits would be closed to Israeli vessels. Egypt then mobilised its forces along its border with Israel, and on 5 June Israel launched what it claimed were a series of preemptive airstrikes against Egyptian airfields. Claims and counterclaims relating to this series of events are one of a number of controversies relating to the conflict.
