Marg Osburne (December 29, 1927 – July 16, 1977) was a Canadian country, folk and gospel singer.

When she was 17 her cousin made her a bet that she did not have the nerve to answer a newspaper advertisement for a female vocalist for CKCW in Moncton.

From being occasional TV guests, the band began a summer series called The Don Messer Show on August 7, 1959 as a replacement for Country Hoedown[4] broadcast on CBC television.

[7] During this period she recorded three songs for Jack Boswell's Marathon label, "Albert County Soil", "Falling Leaves", and "Blues Comin' 'Round".

Osburne continued to perform until July 16, 1977, when she collapsed during a concert in Rocklyn, Ontario and died from the heart attack before she reached the hospital,[8] exactly five years after Charlie Chamberlain's death.
