Avraham Zvi Yehuda Meshi Zahav (19 July 1959 - 29 June 2022) was an Israeli social activist, a member of the Haredi Jewish community, and founder and chairman of ZAKA.

[2] Avraham Zvi Meshi Zahav was born to writer Menachem Saamson Mendel and Sara Zissel, daughter of Rabbi Yosef Scheinberger [he], the secretary of the Edah HaChareidis rabbinical court.

[3] Following allegations of sexual abuse, and the initiation of a police investigation in March 2021, Meshi-Zahav attempted suicide in April 2021 and remained in a coma until he died on 29 June 2022.

The organisation organizes resuscitation courses for women, works to care for neighbors in need, supports Haredi soldiers who are unable to return home, and more.

He also participated in the public committee established by Chief of Staff Aviv Kochavi in December 2019 to examine the forgery of the number of Haredim who have enlisted in the IDF in recent years.

In the early 2010s an allegation of sexual abuse by Yehuda Meshi Zahav was made to the police, who soon closed their investigation; everywhere his name was mentioned "the door was shut".
