Joseph Stein was an American playwright best known for writing the books for such musicals as Fiddler on the Roof and Zorba.

Fiddler on the Roof is a musical with music by Jerry Bock, lyrics by Sheldon Harnick, and book by Joseph Stein, set in the Pale of Settlement of Imperial Russia in or around 1905. It is based on Tevye and his Daughters and other tales by Sholem Aleichem. The story centers on Tevye, a milkman in the village of Anatevka, who attempts to maintain his Jewish religious and cultural traditions as outside influences encroach upon his family's lives. He must cope with the strong-willed actions of his three older daughters who wish to marry for love; their choices of husbands are successively less palatable for Tevye. An edict of the tsar eventually evicts the Jews from their village.
