Rhonda Lea Vincent (b. July 13, 1962, Kirksville, Missouri) is an American bluegrass singer, songwriter, and multi-instrumentalist. In 2000, The Wall Street Journal proclaimed Vincent "the new Queen of Bluegrass".

Vincent's musical career began when she was a child in her family's band The Sally Mountain Show, and has spanned more than four decades. Vincent first achieved success in the bluegrass genre in the 1970s and '80s, earning the respect of her mostly male peers for her mastery of the progressive chord structures and multi-range, fast paced vocals intrinsic to bluegrass music. Vincent is an in-demand guest vocalist for other Bluegrass and Country music performers, appearing on recordings by Dolly Parton, Alan Jackson, Tanya Tucker, Joe Diffie and other notables.
