Frank Sydney Greenop (12 March 1913 – 15 June 1975) was an Australian journalist, editor, linguist, poet and author.
While Greenop was perhaps best known as editor of the then risque magazine, Man, he also had wide-ranging literary tastes and skills.
He wrote numerous articles and fiction stories for Man, as well as dozens of patriotic and sentimental poems, many of which were collected in a volume of his verses published by K.G.
Greenop was also passionate about history and wrote a number of books on historical subjects, including Coast of Tragedy, a history of shipwrecks off the Australian coast; Who Travels Alone, the story of famous New Guinea explorer Nicholas Miklouho-Maclay and The Life and Achievements of Captain James Cook.
In the 1960s he also published a series of twelve children's books (the Moorooba books), with titles such as Lazy Loper, Koalas Drink Dew, Catapult for Tom, Bunyip with a Swag and Magpie Hero, which were illustrated by Col Cameron.
