Coal Miner's Daughter is a 1980 American biographical musical film directed by Michael Apted in a screenplay written by Tom Rickman. It follows the story of country music singer Loretta Lynn, from her birth in a poor family and getting married at 13 to her rise as one of the most successful country musicians.

Based on Lynn's 1976 autobiography of the same name by George Vecsey, the film stars Sissy Spacek as Lynn. Tommy Lee Jones, Beverly D'Angelo and Levon Helm are featured in supporting roles, while Ernest Tubb, Roy Acuff, and Minnie Pearl all make cameo appearances as themselves.

A film on Lynn's life was intended to be made since the release of the autobiography. Production for the film began in late 1979 and Lynn herself chose Spacek to portray her on screen after seeing a photograph of her, despite being unfamiliar with her films. The film's soundtrack featured all Lynn's hit singles which were all sung by Spacek, as well as Patsy Cline's "Sweet Dreams" sung by D'Angelo. The soundtrack reached the top 40 in the U.S. on the Billboard 200 and sold over 500,000 copies, thus being certified gold by the RIAA.

The film grossed $67 million worldwide against a budget of $15 million, becoming the 7th highest-grossing film of 1980.
