Allen Lowrie (born 1948) is a West Australian botanist. He is recognised for his expertise on the genera Drosera and Stylidium.
Lowrie, originally a businessman and inventor, got in contact with the carnivorous flora of western Australia in the late sixties and worked on it as an amateur. As time went on, his hobby turned to a profession and Lowrie discovered and described numerous species (especially Drosera, Byblis and Utricularia), partly together with Neville Marchant. From 1987 to 1998 he published Carnivorous Plants of Australia in three volumes; a fourth is in the making.
Lowrie lives in Duncraig, a Perth suburb, is married and has two daughters.
