"Al-Aqsa is in danger" (Arabic: الأقصى في خطر, romanized: al-Aqṣá fī khaṭar) is an Islamic political slogan that has been used in the context of the Arab–Israeli conflict, referring to the Al-Aqsamosque compound, a site also known as the Temple Mount. The slogan is a rallying call for Muslims to oppose the presence of Jews and Israelis at the compound under the pretext that they are seeking to take it over for the construction of the Third Temple. It also opposes archaeological investigations at the site, which are perceived as undermining the structural foundations of the area; many biblical excavations, particularly by Christian organizations, have sought to unearth more evidence of the Temple in Jerusalem and the true site of Jesus' crucifixion, among others. In mainstream Orthodox Judaism the rebuilding of the Temple is generally left to the coming of the Jewish Messiah and to divine providence.
It was most notably used between 1996 and 2015 for the annual "Al-Aqsa in Danger Festival" that was held by the Palestinian Muslim religious leader Raed Salah and his Islamic Movement in Israel, considered the most well-attended Islamic festival in Israel.

The annual "al-Aqsa in danger" commemorations held in Umm al-Fahm's soccer stadium since 1996 are by far the biggest and best-attended events on the Arab sector's political calendar. Especially prominent was a gathering in 1998, which interposed the commemoration of Muhammad's ascent to heaven from the al-Aqsa mosque-the "night of the nocturnal ascent" (al-isra wal-miraj) - the only holy day in the Islamic calendar linked to the Temple Mount, as well as the fiftieth anniversary of the Nakba (catastrophe referring to Israel's victory and creation in the War of 1948). Attended by over 30,000 people, it far outshone the commemoration ceremonies organized by the "national" (non-Islamic) groups. The latter attracted only a few hundred attendees, even according to sources sympathetic to them.
