Herzl Day (Hebrew: יום הרצל) is an Israeli national holiday celebrated annually on the tenth of the Hebrew month of Iyar, to commemorate the life and vision of Zionist leader Theodor Herzl.

On this day, a state memorial service is held on Mount Herzl in Jerusalem and at IDF camps and schools.

Time is devoted to learning about the achievements and Zionist vision of Theodor Herzl and a symposium in memory of Theordor Herzl is held in Jerusalem to discuss world Zionist issues.

The Knesset holds a special session to mark Herzl Day.

If the Hebrew date, 10 Iyar, falls on Sabbath, Herzl Day is postponed until Sunday.
