Margo Smith (born Betty Lou Miller; April 9, 1942, Dayton, Ohio) is 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".
Smith was born and raised in Ohio. During her childhood she learned how to sing and yodel. After graduating high school, Smith chose to pursue a career in education. For nearly a decade Smith taught elementary school and started a family with her first husband. In her thirties, she decided to begin a singing career full-time and also started songwriting. In 1971, she released her first album titled I'm a Lady and developed a following. By 1975, Smith had signed with 20th Century Fox Records and had her first major hit on the country charts with the song "There I Said It." She had further hits in the 1970s with songs like "Take My Breath Away" and "Don't Break the Heart That Loves You".
In 1979, Smith released the single "Still a Woman" and made significant changes to her musical persona. The transition helped to briefly elevate Smith's commercial country music career and she had further hits. By the early 1980s, Smith regretted making stylistic changes to her career and left her recording contract. She released music independently during the 1980s while also issuing albums through major labels. In the 1990s, Smith transitioned towards Christian music and recording two albums with her daughter, Holly. The pair won awards for their collaborative music and performed for several years. In recent years, Smith has continued performing as a solo act in her current residence located in Florida.
