Yom Hazikaron (Hebrew: יום הזיכרון לחללי מערכות ישראל ולנפגעי פעולות האיבה‎, lit. Israeli Fallen Soldiers and Victims of Terrorism Remembrance Day) is Israel's official Memorial Day. In 2011, Israel honored the memory of soldiers killed in the line of duty and the civilian casualties too.

Yom Hazikaron is the day on which Israel honors its fallen servicemen and women. National memorial services are held in the presence of Israel's top leadership and military personnel. The day opens with a siren the preceding evening at 20:00 (8:00 pm), given that in the Hebrew calendar system, the day begins at sunset. The siren is heard all over the country and lasts for one minute, during which Israelis stop everything (including driving, which stops highways) and stand in silence, commemorating the fallen and showing respect. Many religious Jews say prayers for the souls of the fallen soldiers at this time. The official ceremony to mark the opening of the day takes place at the Western Wall, and the flag of Israel is lowered to half staff.
