Mary Frances Applebey (14 July 1916 – 1 November 2012) was an English civil servant and mental health campaigner.

She was an early director of what is now the charity Mind, but was then the National Association for Mental Health (NAMH).

[5] In 1969, numerous Scientologists joined the NCMH and attempted to ratify as official policy a number of points concerning the treatment of psychiatric patients.

[6] During the 1970s the NCMH became involved with the debate raised by Ann Shearer that mental hospitals should be shut.

Shearer, a Guardian journalist, was joined by Anita Hunt of the Spastics Society and an architect named Sandra Franklin to create the Campaign for the Mentally Handicapped (CMH).
