"An American Trilogy" is a 1972 song medley arranged by country composer Mickey Newbury and popularized by Elvis Presley, who included it as a showstopper in his concerts. The medley uses three 19th-century songs:

"Dixie" – a popular folk song about the southern United States;
"The Battle Hymn of the Republic" – a marching hymn of the Union Army during the American Civil War
"All My Trials" – a Bahamian lullaby related to African American spirituals and widely used by folk music revivalists.
