Israel came to a standstill in tribute to the six million Jews murdered by the Nazis during World War II.
At 10am local time (8am Irish time), Israel observed a two-minute silence, with traffic coming to a halt and the rhythm of everyday life suspended in a symbolic act of remembrance for those who perished.
The commemoration, held each year in April or May in accordance with the Hebrew calendar, is separate from International Holocaust Remembrance Day which is marked on 27 January.
This year's commemoration comes amid a fragile two-week ceasefire with Iran after a deadly war that began on 28 February, when a joint US-Israeli air attack killed Iran's supreme leader Ali Khamenei.
Despite the ceasefire, Israel remains engaged in a war with Hezbollah in south Lebanon, even as separate talks are scheduled to take place between Israeli and Lebanese officials in Washington.
Official ceremonies began yesterday evening with a state event at Yad Vashem, the Holocaust memorial in Jerusalem, attended by senior officials including Prime Minister Benjamin Netanyahu.
Memorial events will take place across the country today.
Officials have said that around 111,000 survivors of Nazi persecution still live in Israel, down from last year's recorded number of 120,507.
