Fiddler on the Roof is a musical with music by Jerry Bock, lyrics by Sheldon Harnick, and book by Joseph Stein, set in csarist Russia in 1905.

Fiddler on the Roof was originally entitled Tevye. It is based on Tevye and his Daughters (or Tevye the Milkman) and other tales by Sholem Aleichem which he wrote in Yiddish and published in 1894. The story centers on Tevye, the father of five daughters, and his attempts to maintain his family and religious traditions while outside influences encroach upon their lives. He must cope with both the strong-willed actions of his three older daughters—each daughter's choice of husband moves progressively further away from established customs—and with the edict of the Tsar that evicts the Jews from their village.

The musical's title stems from a painting by Marc Chagall, one of many surreal paintings he created of Eastern European Jewish life, often including a fiddler. The Fiddler is a metaphor for survival, through tradition and joyfulness, in a life of uncertainty and imbalance.

The original Broadway production of the show, which opened in 1964, was the first musical to surpass the 3,000 performance mark, and it held the record for longest-running Broadway musical for almost 10 years until Grease surpassed its run. The production earned $1,574 for every dollar invested in it.

The show was highly acclaimed and nominated for ten Tony Awards, winning nine, including Best Musical, score, book, direction and choreography. It spawned four Broadway revivals, a successful 1971 film adaptation, and has enjoyed enduring international popularity. It is also a very popular choice for school and community productions.
