Avraham Chaim Naeh (3 May 1890 – 21 July 1954) was a Lubavitcher Hasid[1] and major posek (halachic authority) active during the first half of twentieth century.

The work is of great practical significance since much of Halacha involves specific requirements of precise sizes and quantities.

His father, Rabbi Menachem Mendel Naeh, was the dean of the Magen Avos Yeshiva, founded by the Sdei Chemed.

Many of the dispossessed Jews found refuge in Alexandria, Egypt, where Naeh opened a yeshiva called "Yeshivat Eretz Yisrael".

In 1918, he returned to Israel and served as the personal secretary of the Edah HaChareidis, under Rabbi Yosef Chaim Sonnenfeld,.
