The Caves of Steel is a novel by American writer Isaac Asimov. It is essentially a detective story, and illustrates an idea Asimov advocated, that science fiction is a flavor that can be applied to any literary genre, rather than a limited genre itself.

The book was first published as a serial in Galaxy magazine, from October to December 1953. A Doubleday hardcover followed in 1954.

A television adaptation was made by the BBC and shown in 1964: only a few short excerpts still exist. In June 1989, the book was adapted by Bert Coules as a radio play for the BBC, with Ed Bishop as Elijah Baley and Sam Dastor as R. Daneel Olivaw. More recently, Akiva Goldsman has been hired to produce a movie.

In this novel, Isaac Asimov introduces Elijah Baley and R. Daneel Olivaw, later his favorite protagonists. They live roughly three millennia in Earth's future, a time when hyperspace travel has been discovered, and a few worlds relatively close to Earth have been colonized—fifty planets known as the "Spacer worlds". The Spacer worlds are rich, have low population density (average population of one hundred million each), and use robot labor heavily. Meanwhile, Earth is overpopulated (with a total population of eight billion, three times that of Asimov's 1950s), and strict rules against robots have been passed. The eponymous "caves of steel" are vast city complexes covered by huge metal domes, capable of supporting tens of millions each: the New York City of that era (wherein much of the story is set), encompasses present-day New York City, as well as large tracts of New Jersey.
