"Feet of Clay" is a fantasy novel by British writer Terry Pratchett, the nineteenth book in the Discworld series, published in 1996. The story follows the members of the City Watch, as they attempt to solve murders apparently committed by a golem, as well as the unusual poisoning of the Patrician, Lord Vetinari.

The title is a figure of speech from Hebrew scripture (see feet of clay) and the script used in the book to represent Morporkian being written by a golem resembles the Hebrew alphabet, a reference to golems' origins in Jewish folklore.
