American Epic is a documentary film series about the first recordings of roots music in the United States during the 1920s and their cultural, social and technological impact on North America and the world. Directed and co-written by Bernard MacMahon, the story is told through twelve ethnically and musically diverse musicians who auditioned for and participated in these pioneering recording sessions: The Carter Family, the Memphis Jug Band, Elder J.E. Burch, The Williamson Brothers, Dick Justice, Charley Patton, The Hopi Indian Chanters, Joseph Kekuku, Lydia Mendoza, the Breaux Family, Mississippi John Hurt and Blind Willie Johnson. The film series is the core of the American Epic media franchise, which includes several related works.

The film series was created, written and produced by MacMahon, Allison McGourty and Duke Erikson. It was first broadcast on May 16, 2017, in the United States and was narrated by Robert Redford. The film was the result of ten years of intensive field research and postulated a radically new take on American history, namely that America was democratized through the invention of electrical sound recording and the subsequent auditions the record labels held across North America in the late 1920s, which were open to every ethnic minority and genre of music. The films contained many previously untold stories, a vast amount of previously unseen and extremely rare archival footage and dramatically advanced audio restorations of the 1920s and 1930s recordings.

MacMahon decided all the interviewees had to personally have known the long-deceased subjects of the films, and these interviews were conducted on the location where the musicians had lived, accompanied by panoramic tracking shots of the geographical locations both present and vintage to give a sense of the wildly varied North American landscape and its influence on the music. During pre-production, when MacMahon presented his vision for the films and the archival footage to Robert Redford at their first meeting, Redford pronounced it "America's greatest untold story."

The film series received a number of awards, including the Foxtel Audience Award at the 2016 Sydney Film Festival and the Discovery Award at the 2016 Calgary International Film Festival. It was nominated for a Primetime Emmy. On April 23, 2018, the Focal International Awards nominated American Epic for Best Use of Footage in a History Feature and Best Use of Footage in a Music Production. Many critics have cited the American Epic films as being one of the best music documentaries ever made.
