Margo Smith was an American country and Christian music singer–songwriter. She had several years of country success during the 1970s, which included two number one hits on the Billboard Hot Country Songs chart. In the 1990s, she transitioned towards the Christian market and issued two successful albums. She is also known for her yodeling vocal skills and is often referred to as "The Tennessee Yodeler".

Yodeling is a form of singing which involves repeated and rapid changes of pitch between the low-pitch chest register and the high-pitch head register or falsetto. The English word yodel is derived from the German word jodeln, meaning "to utter the syllable jo". This vocal technique is used in many cultures worldwide. Recent scientific research concerning yodeling and non-Western cultures has shown that music and speech evolved from a common prosodic precursor.
