Melba Joyce Montgomery (born October 14, 1938) is an American country music singer and songwriter. She is known for a series of duet recordings made with George Jones, Gene Pitney and Charlie Louvin. She is also a solo artist, having reached the top of the country charts in 1974 with the song, "No Charge". Born in Tennessee but raised in Alabama, Montgomery had a musical upbringing. Along with her two brothers (songwriters Carl and Earl Montgomery), she placed in a talent contest which brought her to the attention of Roy Acuff. For several years she toured the country as part of his band until she signed with United Artists Records in 1963.

At United Artists, Montgomery collaborated with George Jones on a series of duets. Their first was 1963's "We Must Have Been Out of Our Minds", which became a top five single on the country charts. For several years, Jones and Montgomery toured and recorded together. Among their other singles was "What's in Our Heart", "Let's Invite Them Over" and "Party Pickin'". Montgomery became more identified as a duet artist as the decade progressed. She recorded with both Gene Pitney and Charlie Louvin on several charting country singles. However, her solo career was overshadowed until she moved to Elektra Records in 1973. Her 1974 song about motherhood called "No Charge" became a commercial success in several genres. It was followed by a series of charting singles, including the top 20 "Don't Let the Good Times Fool You" (1975).

Montgomery continued her solo career. In 1977, she reached the top 40 of the country charts again with a cover of the song, "Angel of the Morning". In the eighties, she released several recordings including the album I Still Care and the charting single "Straight Talkin'". In the nineties, Montgomery began working as a songwriter in the country music community. She wrote songs that were recorded by a series of artists. Among them was George Strait, who recorded "What Do You Say to That", which became a top five country single. Montgomery has also continued sporadically releasing music as a country artist. Her most recent album was 2010's Things That Keep You Going, issued on RPM Music.
