Gwendoline "Gwen" Whyte Richardson (5 June 1894[1] – 27 November 1944) was an Australian actress and travel writer, author of On the Diamond Trail in British Guiana (1925).

"[16] Excerpts from the book were reprinted in American and Canadian newspapers, under sensational headlines and with maps and photos of Richardson handling snakes, scorpions, and guns.

[23][24] She lived in the Italian spa town Sirmione in her later years, and was a friend of British actresses Naomi Jacob and Mrs. Patrick Campbell there.

Richardson's description of handling scorpions was included in the 1994 collection Unsuitable for Ladies: An Anthology of Women Travellers, edited by Jane Robinson.

[26] She is mentioned in the novel When the Singing Stops (2012) by Australian writer Di Morrissey,[27] when the main character is inspired by Richardson's book to embark upon similar adventures.
