Haim Hezekiah Medini (Hebrew: חיים חזקיהו מדיני Jerusalem 1834 – Hebron, 1904), also known by the title of his chief halakhic work, Sede Hemed, was a nineteenth century rabbinical scholar.

Although recognized as a scholar and offered a position on the city's rabbinical court, he preferred to devote his time to study and writing.

He also wrote a halachic work entitled Paku'ot Sadeh (Jerusalem, 1900) and Sefer Bakashot (Odessa, 1879) containing piyutim (liturgical poems) which Oriental Jewish communities included in their services on Shabbat and festivals.

During his 33 years in Kara-Su-Bazar he wrote the greater part of his chief work, the Sede Hemed, corresponding with sages around the world to clarify the laws as stated.

[2] Upon hearing that he was suggested as Rishon Letzion, Sepharadi Chief Rabbi, he moved to Hebron in 1901, hoping to be allowed to study in peace.

[8] Sde Hemed, translated from Hebrew means "fields of grace", and is also the name of a moshav in central Israel[9] near Kfar Saba and an elementary school in Maale Adumim.

Sedar Birchat Hachamah and the author's living will were also published in Sdei Chemed Bibliography in Sefer ha-Shanah, by Nahum Sokolov, Warsaw, 1900.
