Sweetheart of the Rodeo is the sixth album by American rock band the Byrds and was released in August 1968 on Columbia Records. Recorded with the addition of country rock pioneer Gram Parsons, it became the first album widely recognized as country rock as well as a seminal progressive country album, and represented a stylistic move away from the psychedelic rock of the band's previous LP, The Notorious Byrd Brothers. The Byrds had occasionally experimented with country music on their four previous albums, but Sweetheart of the Rodeo represented their fullest immersion into the genre up to that point in time. The album was responsible for bringing Parsons, who had joined the Byrds in February 1968 prior to the start of recording, to the attention of a mainstream rock audience for the first time. Thus, the album is an important chapter in Parsons' crusade to make country music fashionable for a young audience.

The Byrds were an American rock band formed in Los Angeles, California, in 1964. The band underwent multiple lineup changes throughout its existence, with frontman Roger McGuinn remaining the sole consistent member. Although their time as one of the most popular groups in the world only lasted for a short period in the mid-1960s, the Byrds are considered by critics to be among the most influential rock acts of their era. Their signature blend of clear harmony singing and McGuinn's jangly 12-string Rickenbacker guitar was "absorbed into the vocabulary of rock" and has continued to be influential.
