Avichai Rontzki (Hebrew: אביחי רונצקי; October 10, 1951 – April 1, 2018) was an Israeli Chief Military Rabbi of the Israel Defense Forces.

"In December 2014, after it became clear that the Knesset's coalition would dissolve, and new elections would be called, Rontzi announced he expected to run in the primaries for Bayit Yehudi's list.

[6] He gave Torah classes in jails, and conducted a tour of Hebron for soldiers in Military Intelligence in which they met with Rabbi Dov Lior.

In addition, he revealed that a female Religion Officer would join the Military Rabbinate for the first time to serve the needs of religious women soldiers.

[12] His attitude towards women soldiers has been criticised by several Knesset members, who demanded that Rontzki be dismissed from his post as IDF's chief rabbi.

[13] The Israeli human rights organization Yesh Din called on Defense Minister Ehud Barak to immediately remove Rontzki from his post as chief military rabbi, due to his conduct during Operation Cast Lead.

The [military] rabbinate is bringing religion in through the back door, in a dangerous manner, and harming the IDF's ability to fulfill its mission".

[9] In December 2009, it was reported that Defense Minister of Israel Ehud Barak and Chief of General Staff Gabi Ashkenazi will not extend Rontzki's service past the summer of 2010.

[15] Referring to the Gilad Shalit prisoner exchange, Rontzki said in an interview to Arutz Sheva in October 2011 that Israeli soldiers should no longer arrest convicted terrorists, but instead "kill them in their beds".
