Yad Vashem (Hebrew: יָד וַשֵׁם; lit. 'a memorial and a name') is Israel's official memorial to the victims of the Holocaust. It is dedicated to preserving the memory of the Jews who were murdered; echoing the stories of the survivors; honoring Jews who fought against their Nazi oppressors and gentiles who selflessly aided Jews in need; and researching the phenomenon of the Holocaust in particular and genocide in general, with the aim of avoiding such events in the future. Yad Vashem's vision, as stated on its website, is: "To lead the documentation, research, education and commemoration of the Holocaust, and to convey the chronicles of this singular Jewish and human event to every person in Israel, to the Jewish people, and to every significant and relevant audience worldwide."

Established in 1953, Yad Vashem is located on the Mount of Remembrance, on the western slope of Mount Herzl, a height in western Jerusalem, 804 meters (2,638 ft) above sea level and adjacent to the Jerusalem Forest. The memorial consists of a 180-dunam (18.0 ha; 44.5-acre) complex containing two types of facilities: some dedicated to the scientific study of the Holocaust, and memorials and museums catering to the needs of the larger public. Among the former there are an International Research Institute for Holocaust Research, an archives, a library, a publishing house and the International School for Holocaust Studies; the latter include the Holocaust History Museum, memorial sites such as the Children's Memorial and the Hall of Remembrance, the Museum of Holocaust Art, sculptures, outdoor commemorative sites such as the Valley of the Communities, as well as a synagogue.

A core goal of Yad Vashem's founders was to recognize non-Jews who, at personal risk and without financial or evangelistic motives, chose to save Jews from the ongoing genocide during the Holocaust. Those recognized by Israel as Righteous Among the Nations are honored in a section of Yad Vashem known as the Garden of the Righteous Among the Nations.

Yad Vashem is the second-most-visited Israeli tourist site, after the Western Wall, with approximately one million visitors each year. It charges no admission fee.
