Yaakov Eliezer Kahana Shapira (Hebrew: יעקב אלעזר כהנא שפירא; born 26 December 1950) is the rosh yeshiva of the Mercaz HaRav yeshiva in Jerusalem and a member of the Chief Rabbinate Council.

[1][2][3] Shapiro was born in Jerusalem to Rabbi Avraham Shapira, the previous Rosh Yeshiva of Mercaz HaRav, and his wife, Penina Perl.

He studied in the Yashlatz yeshiva high school, and then at Yeshivat Mercaz Harav.

In 2008, during his first year as Rosh Yeshiva, an Arab from Jabel Mukaber in East Jerusalem entered the yeshiva with a gun and began firing indiscriminately, killing eight students and wounding 15 others.

In October 2014, he submitted his candidacy for the position of Chief Rabbi of Jerusalem, but withdrew from the race on election day.
