Coco is a 1969 Broadway musical with a book and lyrics by Alan Jay Lerner and music by André Previn, inspired by the life of Coco Chanel. Katharine Hepburn starred in the title role, her first and only in a stage musical.

Gabrielle Bonheur "Coco" Chanel was a French fashion designer and businesswoman. The founder and namesake of the Chanel brand, she was credited in the post–World War I era with popularizing a sporty, casual chic as the feminine standard of style. This replaced the "corseted silhouette" that had earlier been dominant with a style that was simpler, far less time-consuming to put on and remove, more comfortable, and less expensive, all without sacrificing elegance. She is the only fashion designer listed on Time magazine's list of the 100 most influential people of the 20th century. A prolific fashion creator, Chanel extended her influence beyond couture clothing, realizing her aesthetic design in jewellery, handbags, and fragrance. Her signature scent, Chanel No. 5, has become an iconic product, and Chanel herself designed her famed interlocked-CC monogram, which has been in use since the 1920s.
