Ezra Attiya (Hebrew: עזרא עטייה; Arabic: عزرا عطية; 31 January 1885 – 25 May 1970) was one of the greatest teachers of Torah in the Sephardic Jewish world during the 20th century. He was rosh yeshiva of Porat Yosef Yeshiva in Jerusalem for 45 years, nurturing thousands of students who, together with their students, constitute the bulk of Sephardic Torah leadership today.

Attiya was born on 31 January 1885 (Tu Bishvat 5645 on the Jewish calendar) in Aleppo, Syria, which was then part of the Ottoman Empire. His parents, Yitzchak and Leah, had lost several children in infancy, and before his birth they traveled to the gravesite of the Prophet Ezra to pray that if the child they were expecting was a boy, they would name him Ezra and see that he dedicated himself to a life of Torah. He had one brother, Eliyahu. His father, a respected Aleppo melamed (teacher), was a direct descendant of Shem Tov Attiya, a disciple of Joseph Caro, author of the Shulchan Aruch.

When Attiya was 16 years old, his family immigrated to Jerusalem's Old City, to which a large number of rabbis from Aleppo had immigrated. Soon after, his father died, leaving an impoverished widow and two orphans. While his mother hired herself out for domestic work in the homes of wealthy people, young Ezra decided to devote his life to Torah study. He went to learn, pray, and sleep on a bench in a small beth midrash in the Bukharim neighborhood of the New City called Shoshanim LeDavid, covering vast amounts of the Talmud with commentaries and poskim (halakhic decisors). As money was scarce in his household, he sustained himself with a nightly meal of dry pita seasoned with salt. In his old age, he told his students, "When I was young, I studied Torah through hardship. If we were truly fortunate, my mother and I had a whole pita to share. On rare occasions we also had an egg, which we divided in half. But the hunger did not bother me in the least."

In 1907, Ezra Harari-Raful, another Aleppo immigrant, established Yeshivat Ohel Moed in Jerusalem. Attiya was asked to join its staff along with distinguished Sephardic Rabbis Yosef Yedid HaLevi, head of the Sephardic beit din (rabbinical court) of Jerusalem, Shlomo Laniado, and Avraham Haim Ades. He served as maggid shiur.

In 1909, Attiya married Bolissa Salem, daughter of Avraham Salem, a kabbalist. In 1911 their first son was born, but died in infancy.

At the beginning of World War I, there was a general mobilization for the Turkish army and all able-bodied men were snatched off the streets. Attiya's brother Eliyahu died of pneumonia in the Turkish army. Two of the leading Sephardic sages of Jerusalem, Chaim Shaul Dweck Hakohen and Avraham Ades, smuggled Attiya to Egypt using a forged Russian passport, which at that time did not require a photograph.

Attiya settled in Cairo. At first he attempted to go into business, but quickly lost most of his money. Then he met Nissim Nachum, a wealthy refugee who knew him from Jerusalem. With Nachum's backing, Attiya opened a yeshiva named Ahavah VeAchvah in the basement of the Cairo rabbinate. Under his direction, the yeshiva grew to 100 students, attracting many from secular backgrounds. Attiya also gave classes to working men, and was a dayan on the Cairo beit din. After World War I ended his wife joined him. They and their two children returned to Jerusalem in 1922.

In Jerusalem, Attiya returned to his teaching position at Ohel Mo'ed Yeshiva. He also studied privately with Chaim Shaul Dweck and Solomon Eliezer Alfandari. When Porat Yosef Yeshiva opened in 1923, Ohel Moed was merged with the new yeshiva and Attiya was appointed as the mashgiach ruchani. Following the sudden death of the rosh yeshiva, Shlomo Laniado, in 1925, Attiya was named his successor. He served as rosh yeshiva for 45 years.
