Anthony Wilden (14 December 1935, London, England) is a writer, social theorist, college lecturer, and consultant. Wilden has published numerous books and articles which intersect a number of fields, including systems theory, film theory, structuralism, cybernetics, psychiatry, anthropological theory, water control projects, urban ecosystems, resource conservation, and communications and social relations.

Wilden is credited with one of the first significant introductions to the work of Jacques Lacan in the Anglo-Saxon world, particularly in his role as one of Lacan's early English translators. Today and into the 21st century Wilden's work (and consequent reputation) is arguably more influential in the fields of communication theory, ecology and social interaction. These fields of study evolved out of a long scholarly tradition of "interactional semiotics" that originated with Plato's Cratylus. Along with such figures as Gregory Bateson (ie., Steps to an Ecology of Mind), R. D. Laing (ie., Sanity, Madness and the Family), and Walker Percy (ie., Lost in the Cosmos), Wilden is considered one of this tradition's contemporary (modern and postmodern) pioneers.
