Rabbi Yom-Tov Ehrlich (Hebrew: יום-טוב עהרליך) (1914–1990) was a renowned Hasidic musician, composer, lyricist, recording artist, and popular entertainer known for his popular Yiddish music albums.

He was born in Kozhan Gorodok and raised in the nearby Davyd-Haradok, both then part of the Russian Empire.

His grandfather, Yom Tov Simcha Ehrlich, was an aide to Rabbi Aharon of Karlin, an early leader of the Hasidic movement.

Ehrlich himself was a Hasid of the late Rabbi Yochanan Perlow of Karlin.

Some of Ehrlich's favorite songs were later recorded by other popular Hasidic entertainers, such as Mordechai Ben David, Lipa Shmeltzer,Levy Falkowitz and Avraham Fried, although Ehrlich himself used Russian classical and folk melodies to accompany his own Yiddish lyrics.
