A Holocaust memorial day or Holocaust remembrance day is an annual observance to commemorate the victims of the Holocaust, the genocide of six million Jews and of millions of other Holocaust victims by Nazi Germany and its collaborators. Many countries, primarily in Europe, have designated national dates of commemoration. In 2005, the United Nations instituted an international observance, International Holocaust Remembrance Day.

Many observances fall on 27 January, the anniversary of the liberation of Auschwitz concentration camp in 1945, while other countries selected separate dates, often to mark anniversaries of national events during the Holocaust. Holocaust remembrance days often include efforts to combat hatred and antisemitism.
