Maybelle Carter (May 10, 1909 – October 23, 1978) was an American Country music musician.

She was born Maybelle Addington in Nickelsville, Virginia, the daughter of Hugh Jackson Addington and Margaret S. Kilgore.

On March 13, 1926, Maybelle married Ezra J. Carter. They had three daughters, Helen, Valerie June and Anita .

She was a member of the original Carter Family, which was formed in 1927 by her brother-in-law, A. P. Carter, who was married to her cousin, Sara, also a part of the trio. It was perhaps the first commercial rural Country music group. Maybelle was the guitarist and also played autoharp and banjo; she created a unique sound for the group with her innovative bass tunings.

She was widely respected and loved by the Grand Ole Opry community of the early 1950s, and was popularly known as "Mother Maybelle."

Maybelle Carter is interred in Hendersonville Memory Gardens, Hendersonville, Tennessee.

In 1993, her image appeared on a U.S. postage stamp honoring the Carter Family.
