Eliezer Yehuda Waldenberg (Hebrew: הרב אליעזר יהודה וולדנברג; December 10, 1915 – November 21, 2006) was a rabbi, posek, and dayan in Jerusalem.

For many years, Waldenberg served as a community rabbi at a small synagogue on Jaffa Road adjacent to the Shaare Tzedek Hospital.

When preparing to treat a patient with a contagious disease, the physician should pray to G-d for special guidance and protection since he is endangering his own life.

A military physician is permitted to render medical care to a wounded soldier in a combat zone although he is endangering his own life.

Similarly, another soldier is allowed to place his own life in danger in order to rescue a wounded comrade from the combat zone.

[11]Waldenberg ruled sex reassignment surgery to be permissible in the case of a baby born androgynous where one set of organs were more developed.

And if that is the case, it appears that there is no concern about kevod ha-beriyot greater than the one that arises in connection with ensuring that a deaf person does not suffer embarrassment because of being unable to hear what people say to him.

This produces a concern about kevod ha-beriyot greater than in connection with the matters discussed earlier, to which must be added his distress at forgoing public worship and being unable to hear the Torah reading and the responses to Kaddish and Kedusha, etc.

In this work he takes issue with many positions of former chief rabbis Yitzhak HaLevi Herzog, Shlomo Goren, and Isser Yehuda Unterman.

He writes in support of yeshiva students' exemption from compulsory military service in the Israel Defense Forces, considering that through the merit of their Torah learning they help protect the country.

Most legal authorities required workers to bring their employer to a beit din (religious court) before resorting to a strike.
