Linda Martell (born Thelma Bynem; June 4, 1941) is an American singer. She became the first commercially successful black female artist in the country music field and the first to play the Grand Ole Opry. As one of the first African-American country performers, Martell helped influence the careers of future Nashville artists of color.

Born and raised in South Carolina, Martell listened to country, gospel and R&B music. In her teens, she formed a singing trio with her family titled Linda Martell and the Anglos. During the 1960s, the group recorded a handful of R&B singles and sang alongside other black performers. However, the group had little success and soon parted ways. Performing as a solo act, Martell was discovered singing country music on an air force base. This led to an introduction to producer Shelby Singleton, who signed her to his Nashville label in 1969. The same year, the label released her country cover of "Color Him Father". The song became a top 10 single on the Billboard charts and her debut album followed in 1970.

Martell made several appearances on country music television programs and released two more singles with Plantation. She also made her first appearance on the Grand Ole Opry during this time. She later performed there 12 times. Following a series of business conflicts with her manager (Duke Raymer) and producer, Martell left her recording contract. She then retired from the country music industry in 1974 following a lack of success. Over the next several decades, she lived in various states and continued performing music. To make a living, she worked in public education and returned to South Carolina in the 1990s.

In 2021, the CMT Music Awards honored Martell with the Equal Play Award. In March 2024, Martell was featured on two tracks of Beyoncé's eighth studio album Cowboy Carter, including "Spaghettii", which generated her first Grammy Awards nomination.
