Johanna Drucker (born May 30, 1952) is an American author, book artist, visual theorist, and cultural critic.

Most recently, her scholarship has focused on information visualization, "which draws heavily on models from the empirical sciences, where approaches based on representation and transparency prevail."

In contrast to this approach, Drucker stresses the rhetorical and performative nature of visualization, with emphasis on interpretation.

In the process, she theorizes the modernist tradition of visual art through a rhetoric of representation rather than from a formalist or historical approach, particularly regarding space, the ontology of the object, and the production of subjectivity.

Drucker emphasized, for the first time, the extent to which typographic activity furthered debates about the very nature and function of the avant-garde.

Analyzing such artistic luminaries as William Morris, Marcel Duchamp, and Max Ernst, Drucker considers the book as metaphor, poem, and narrative or non-narrative sequence by situating its historical, theoretical, sociological, and technical aspects within 20th century avant-garde art movements.

In collaboration with Brad Freeman, Drucker produced Nova Reperta (2000), inspired by illustrations by the sixteenth-century Flemish artist Johannes Stradanus.

[11] She collaborated again with Freeman on Emerging Sentience (2001), a work that reflects Drucker's interest in the literature of artificial intelligence and the development of digital media.
