Akiva Ehrenfeld (Hebrew: עקיבא עהרענפעלד) (1923 – 16 August 2012) was an Orthodox Jewish rabbi who helped establish the Kiryat Mattersdorf and Unsdorf neighborhoods of northern Jerusalem.

Two months later, Akiva's father established Yeshivas Chasan Sofer on the Lower East Side.

Ehrenfeld sold some of the first apartments in the neighborhood to Rabbi Chaim Pinchas Scheinberg, his family members and students,[7] encouraging Scheinberg to relocate his yeshiva, Torah Ore, to Jerusalem from Bensonhurst, Brooklyn by offering attractive terms for apartments and land for the yeshiva[8] at the southeast end of the neighborhood.

[1] He established close ties with the government of Austria to obtain funding for several institutions, including a kindergarten and the Neveh Simcha nursing home.

Instead, he acted as president of Kiryat Mattersdorf while his only son, Rabbi Yitzchok Yechiel Ehrenfeld, became the Rav of the neighborhood.

He died on August 16, 2012, at Shaare Zedek Medical Center and was buried that night on Har HaMenuchot[1] near the grave of his father.
