Terry Alan Fox (May 10, 1943 – October 14, 2008) was an American conceptual artist known for his work in performance art, video art and sculpture. He was one of the first generation conceptual artists and was a central participant in West Coast conceptual art movements of the late 1960s and early 1970s. Fox was active in the San Francisco Bay Area and Europe, living and working in Liège, Belgium in the later part of his life.

Fox was born in 1943 in Seattle, Washington, United States. At the age of seventeen in 1960, he was diagnosed with Hodgkin's disease, a type of cancer that affects the lymphatic system. Several of his artworks referenced the cycles of illness and wellness. He studied art at Cornish College of the Arts (1961) at night, while working at Boeing Aircraft. He continued his studies at Accademia di Belle Arti di Roma (1962).

Fox was an important figure in post-minimal sculpture, conceptual art, performance, and video art on the West Coast. Before permanently moving to Europe, he was based in San Francisco in the late 1960s and 1970s and was associated with the underground art scene. Fox moved often and lived in the following cities: Rome (1962), San Francisco (1963–1966, late 1968–1978), Paris (1967–early 1968, 1972), Naples (1983–1984), New York City (1978–1979). In 1980, he moved to Europe permanently and eventually settled in Liège, Belgium.

Fox died in Cologne, Germany on October 14, 2008.

In 1963, Fox relocated to San Francisco where he created paintings inspired by Arthur Rimbaud until 1967. He was working at the post office at this time in preparation for traveling abroad. In 1966, he produced a series of "black mirror paintings"; these were made by spraying opaque black paint on clear glass, effectively producing a mirror surface. The black paint was hand etched with faint words and scratches. Occasionally blue paint would be applied to the scratched areas on the back side of the glass such that viewers would see themselves reflected in the black mirrors.

In 1967 Fox moved to Amsterdam where he continued painting; then moved on to create his first "actions". These performative works were inspired by the Fluxus movement. The following year he relocated to Paris where he began to produce process-oriented sculptures, "street actions", as well as two dimensional works on paper such as drawings and frottages from various surfaces. Fox collaborated with the painter William T. Wiley on the process piece, Dust Exchange, which he considered to be his first work of sculpture.

He then traveled back to San Francisco in 1969 where he produced a series of public art events titled Pubic Theater. The following year Reese Palley Gallery presented the first solo exhibition of his work, which included Fox's first sound art works. Also in 1970, Fox collaborated on a performance, entitled Isolation Unit, with the German artist, Joseph Beuys. This was presented at the Kunstakademie Düsseldorf (where Beuys was teaching at that time); a sound work was produced in conjunction with the performance and published in the form of an EP record.

In 1971, Fox was awarded a grant from the National Endowment for the Arts which he used to purchase a Portapak analogue videotape recorder and sound equipment. He was largely self taught in video art.
