Frederick Manson Bailey CMG (8 March 1827 – 25 June 1915) was a botanist active in Australia, who made valuable contributions to the characterisation of the flora of Queensland.

[3] In 1874, Bailey published a Handbook to the Ferns of Queensland, and in the following year was made botanist to the board appointed to investigate diseases of livestock and plants.

He published in 1881 The Fern World of Australia, and in 1883 appeared A Synopsis of the Queensland Flora, a work of nearly 900 pages to which supplementary volumes were added in later years.

[3] In 1891, he wrote Botany:Contributions to the Queensland Flora (on behalf of the Department of Agriculture, Brisbane) as colonial botanist.

In the meantime, there had been A Companion for the Queensland Student of Plant Life and Botany Abridged (1897), a revised reissue of two earlier pamphlets.
