Malcolm Bell Wiseman (May 23, 1925 – February 24, 2019) was an American bluegrass singer.

His musical career began as upright bass player in the Cumberland Mountain Folks, the band of country singer Molly O'Day. When Lester Flatt and Earl Scruggs left Bill Monroe's band, Wiseman became the guitarist for their new band, the Foggy Mountain Boys. Later he played with Bill Monroe's Bluegrass Boys.

In 1951, his first solo single, "'Tis Sweet to Be Remembered", was released. According to Rolling Stone this song "catapulted him to solo stardom".

He was co-founder of the Country Music Association (CMA) and was its last living co-founder. In 1958, the original CMA board was formed with help from Wiseman to save the popularity of country music from rock & roll. He also served as the first secretary of CMA.[2] From 1966 to 1970, Wiseman served as director of the WWVA Jamboree.

In 1986 he co-founded the International Bluegrass Music Association (IBMA) which was another influential bluegrass music body.

Wiseman was referred to by a disc jockey as "The Voice with a Heart", a title which became popular among his fans. He was popular for his interpretations of songs on Dot Records such as "Shackles and Chains", "I'll Be All Smiles Tonight", "Jimmy Brown the Newsboy", and "Love Letters in the Sand".
