Sue Donaldson (also known as Susan Cliffe; born 1962) is a Canadian writer and philosopher. She is a research fellow affiliated with the Department of Philosophy at Queen's University, where she is the co-founder of the Animals in Philosophy, Politics, Law and Ethics (APPLE) research cluster.
Donaldson is a vegan and a philosopher of animal rights. She published a vegan cookbook, Foods That Don't Bite Back, in 2003. She has also co-authored numerous articles in peer-reviewed academic journals on the topic of animal rights.
She published Zoopolis: A Political Theory of Animal Rights, co-written with Will Kymlicka, in 2011. In this book, as well as their other co-authored work on animal ethics, Donaldson and Kymlicka argue for a group-differentiated political conception of animal rights. Drawing upon citizenship theory, they argue that although all animals should be protected by the same fundamental rights, individual animals should have different rights (and different responsibilities) depending on their group membership. Animals who form a part of mixed human/animal society (domesticated animals) should be conceived of as citizens, while animals who are reliant upon the mixed society without being a part of it (liminal animals) should be conceived of as denizens. Wild animals, who live wholly or mostly separately from the mixed human/animal society, should be conceived of as sovereign over their own territory. Intervention to reduce wild animal suffering would accordingly be acceptable if compatible with respect for their sovereignty.
