The Most Important Man is an opera in three acts with music and libretto by Gian Carlo Menotti. Commissioned by Julius Rudel for the New York City Opera, the work premiered at Lincoln Center in 1971 in a production directed by Menotti with sets designed by Oliver Smith and costumes by Frank Thompson. An opera focusing on racial tensions in Africa with a central black hero, the work was poorly received by most critics. However, Menotti personally believed that this was one of his best operas on par with The Consul and The Saint of Bleecker Street. The work's first European performance was at the Teatro Lirico Giuseppe Verdi in Trieste, Italy, on January 17, 1972. The opera uses Menotti's characteristic lyrical style which is inspired by Puccini and the Italian verismo opera tradition. In this work he infuses African percussion and rhythms, much in the way Puccini infused Asian inspired melodies and musical practices into his opera Madama Butterfly.

Gian Carlo Menotti was an Italian-American composer, librettist, director, and playwright who is primarily known for his output of 25 operas. Although he often referred to himself as an American composer, he kept his Italian citizenship. One of the most frequently performed opera composers of the 20th century, his most successful works were written in the 1940s and 1950s. Highly influenced by Giacomo Puccini and Modest Mussorgsky, Menotti further developed the verismo tradition of opera in the post-World War II era. Rejecting atonality and the aesthetic of the Second Viennese School, Menotti's music is characterized by expressive lyricism which carefully sets language to natural rhythms in ways that highlight textual meaning and underscore dramatic intent.
