Franklin Delano Roosevelt Wakefield (born June 26, 1934) is an American mandolin player. He is notable as a great bluegrass player and for his significant innovations that have shaped the way many musicians play the mandolin. Wakefield's pedigree as a bluegrass giant can be seen through his collaborations with a number of important and well-known bands, including Red Allen, Jimmy Martin, Don Reno, Jerry Garcia, Ralph Stanley, Bill Monroe, David Grisman and the Greenbriar Boys. In such roles Wakefield impressed bluegrass enthusiasts with his aggressive driving bluegrass style and precision playing reminiscent of Bill Monroe. But so too is he known as a chief innovator on the mandolin, forging his own distinctive style that melds bluegrass traditions with blues influences and even classical music. Student, and mandolin legend in his own right, David Grisman said of Wakefield's influence, "He split the bluegrass mandolin atom. Some of us, obviously, will never be the same again." Wakefield continues to record and tour nationally; he remains one of the most colorful, unique and exciting voices in American music.

Born into a musical family in Emory Gap, Tennessee, Wakefield by age eight already knew how to play harmonica, guitar and bass. In 1950, his family moved to Dayton, Ohio. At the age of 16 he had switched to the mandolin and began playing music with his brother Ralph on guitar. The duo called themselves The Wakefield Brothers and in 1951, made their first radio appearance playing gospel and old-time music on WHIO in Dayton.

In 1952 Wakefield began a long and to productive collaboration with the bluegrass singer and guitar player, Red Allen. For the next 3 years Wakefield toured with Red Allen and the Blue Ridge Mountain Boys. Through the rest of the decade Wakefield also toured with Jimmy Martin and the Sunny Mountain Boys as well as the Chain Mountain Boys, with whom he recorded his first 45 RPM--which included his now most famous bluegrass composition, "New Camptown Races". In 1958 Wakefield reunited with Red Allen and his band the Kentuckians. The popular Kentuckians cut many 45s in following years, had a weekly radio show, and even played at Carnegie Hall in 1963. Important CD recordings surviving from this period of Wakefield's career include Red Allen and Frank Wakefield: the Kitchen Tapes and Red Allen: the Folkway Years 1964-1983. In 1960, Wakefield moved to Washington, DC with Red Allen and there began giving private lessons. One of his students at this time was a young David Grisman.

In the mid 1960s Wakefield began playing mandolin with the very popular Greenbriar Boys as well as appearing with Ralph Stanley. Also in this period he began turning to new influences, composing classical mandolin sonatas and arranging classical pieces for traditional blugrass instruments. This innovative style offered him the opportunity to play with the New York Philharmonic, led by Leonard Bernstein in 1967 and an invitation to appear as a guest with the Boston Pops in 1968.

By the 1970s Wakefield launched a solo career. He released his first solo album in 1972 and his second in 1975 backed up by bluegrass heavyweights Don Reno and Chubby Wise. He toured with Jerry Garcia, and New Riders of the Purple Sage and opened for the Grateful Dead. By mid-decade Wakefield began working with his newly formed band, The Good Ol' Boys with whom he would enjoy a productive collaboration until the mid 1980s. Since 1989 he has toured with the Frank Wakefield Band. In 1999 he earned a Grammy Nomination for best bluegrass album of the year for his work on the album Bluegrass Mandolin Extravaganza on which he played with fellow mandolin greats Sam Bush, David Grisman, Ronnie McCoury, Jesse McReynolds, Bobby Osborne, Ricky Skaggs and Buck White.
