Alexander Dancyg (Hebrew: אלכס דנציג; 21 July 1948 – 2024) was a Polish-born Israeli historian, Yad Vashem Institute contributor, farmer and an active advocate of Polish-Jewish dialogue.

His parents came from Warsaw, and spent the German occupation of World War II in the so-called Eastern Borderlands hiding under a false name: Danecki.

In 1986, Dancyg returned to Poland for the first time in three decades and visited the Auschwitz death camp, which fuelled his interest in Holocaust education and the complicated Polish–Jewish relations[1][2] of the post-Communist period.

In 1990, he started working with Yad Vashem, preparing tour guides chosen to accompany Israeli groups on their visits to Poland.

The Polish Ministry of Foreign Affairs also released a statement that it was unable to confirm the claims of Dancyg's death at the time.

[4][16][17] On 20 August 2024 the bodies of Dancyg and fellow hostages Yoram Metzger, Chaim Peri, Avraham Munder (also from Nir Oz), Yagev Buchshtav and Nadav Popplewell (from kibbutz Nirim) were recovered from a tunnel in Khan Younis.

[18] On 22 August it was announced that bullet wounds had been found in the bodies of all six hostages, who had been probably shot by their guards to prevent a rescue during fighting in Khan Younis, earlier in the year.

"[21] Described as an "idealistic kibbutznik and a flesh-and-blood socialist", Dancyg was an opponent of nationalism, and was known for his sharp critique of the Israeli right as well as Polish anti-Jewish phobias.

Directed by Krzysztof Bukowski, it received the "Bronze Hobby-Horse" Special Award at the National Short Film Festival in Kraków in 2000.

[25] In 2013, the Chapter of the Polcul Foundation awarded him the Eudoxja Rakowska Prize for "his long-standing activity for the historical education of Israeli and Polish youth".
