Umm Kulthum (Arabic: أم كلثوم‎ ʾUmm Kulṯūm; Egyptian Arabic pronunciation: [omme kælˈsuːm]; born فاطمة إبراهيم السيد البلتاجي Fātimah ʾIbrāhīm as-Sayyid al-Biltāǧī, [ˈfɑtˤmɑ (ʔe)bɾˤɑˈhiːm esˈsæjjed elbelˈtæːɡi]; see Kunya) (December 30, 1898^{[citation needed]}–February 3, 1975) was an Egyptian singer, songwriter, and actress. Born in Tamay ez-Zahayra village, which belongs to El Senbellawein, she is known as "the star of the East" (kawkab el-sharq). More than three decades after her death, she is widely regarded as the greatest female singer in Arab music history.

Umm Kulthum was born in Tamay ez-Zahayra village in El Senbellawein, Dakahlia Governorate, Egypt, in Dakahlia, in the Nile Delta, near the Mediterranean Sea. Her birth date is unconfirmed, as birth registration was not enforced throughout the Arab world. The Egyptian Ministry of Information seems to have given either December 31, 1898, or December 31, 1904. She was likely born some time between these two dates.

At a young age, she showed exceptional singing talent. Her father, an Imam, taught her to recite the Qur'an, and she is said to have memorized the entire book. When she was 12 years old, her father disguised her as a young boy and entered her in a small performing troupe that he directed. At the age of 16, she was noticed by Mohamed Aboul Ela, a modestly famous singer, who taught her the old classical repertoire. A few years later, she met the famous composer and oudist Zakariyya Ahmad, who invited her to come to Cairo. Although she made several visits to Cairo in the early 1920s, she waited until 1923 before permanently moving there. She was invited on several occasions to the house of Amin Beh Al Mahdy, who taught her how to play the oud, a type of lute. She developed a very close relationship to Rawheya Al Mahdi, daughter of Amin, and became her closest friend. Kulthum even attended Rawheya's daughter's wedding, although she always tried to avoid public appearances.
