Rabbi Yisrael Ariel (Hebrew: ישראל אריאל; born Yisrael Stieglitz[1] 15 August 1939) was the chief rabbi of the evacuated Israeli settlement of Yamit in the Sinai Peninsula during the years when the Sinai was controlled by Israel, and the founder of the Temple Institute (Machon HaMikdash).

[2] As a young man, Ariel served in the Paratroopers Brigade unit that captured the Temple Mount in the Six-Day War[dubious – discuss].

[2] For the 1981 Knesset elections, Ariel ran as number two on the Kach list, with Rabbi Meir Kahane in the number-one spot.

[4] In December 2006, he was briefly arrested and interrogated by Israeli police after confronting General Elazar Stern.

In 2015, he described Jewish religious terrorism suspects who were banned from entering the West Bank due to vandalism, as praiseworthy.
