Eye in the Sky is a science fiction novel written by Philip K. Dick and originally published in 1957.

The title refers to the gigantic, all-seeing eye of God; at least, that is, as a manifestation of one Arthur Silvester's personal worldview. He is an elderly schismatic Bábí World War II army veteran whose inner life is initially forcibly imposed on several other characters as the result of the involuntary formation of a gestalt consciousness after a nuclear accident.

While on a visit to the (fictional) Belmont Bevatron in then near-future 1957, eight people become stuck in a series of subtly unreal worlds, caused by the malfunction of the particle accelerator. These are later revealed to be solipsistic manifestations, bringing the story in line with Dick's penchant for subjective realities. As well as his future discussions of theology and fears about McCarthy-era authoritarianism, the novel skewers several human foibles.

Jack Hamilton, the central protagonist, is dismissed from his job at the California Maintenance Labs due to McCarthy-era paranoia about his wife Marsha's left-wing political sympathies. Other affected members of the injured touring party include Bill Laws, an African-American Physics PhD, who is employed as a tour guide within the plant. The above-mentioned Arthur Silvester is an elderly political conservative and believer in an obsolete geocentric cosmology, derived from a schismatic Bábí offshoot. Joan Reiss is a pathologically paranoid woman. Edith Pritchet is a maternal but censorious elderly woman. In succession, the group moves through solipsistic personalized alternate realities related to the beliefs and opinions of Arthur Silvester, Pritchet, Reiss and a hardline Marxist caricature of contemporary US society. Marsha Hamilton's subconscious perceptions, however, did not create this alternate reality, as most of their companions and even her own husband, originally thought. It originates instead from an unexpected source, revealed as Charles McFeyffe, a Communist sympathizer who works as chief security officer in the California Maintenance Labs plant
