Vito Hannibal Acconci (born January 24, 1940) is a Bronx, New York-born, Brooklyn-based architect, landscape architect, and installation artist.

His father was an Italian immigrant who took him to museums and opera houses and gave him his first arts education. Vito attended Regis High School on New York City. He received a B.A. in literature from the College of the Holy Cross in 1962 and an M.F.A. in literature and poetry from the University of Iowa.

Acconci began his career as a poet, editing 0 TO 9 with Bernadette Mayer in the late 1960s. In the late 1960s, Acconci transformed himself into a performance and video artist using his own body as a subject for photography, film, video, and performance. His performance and video work was marked heavily by confrontation and Situationism. In the mid 1970s, Acconci expanded his metier into the world of audio/visual installations.

During the 1980s he invited viewers to create artwork by activating machinery that erected shelters and signs. He also turned to the creation of furniture and to prototypes of houses and gardens in the late 1980s.

More recently, the artist has focused on architecture and landscape design that integrates public and private space.
