Silence: Lectures and Writings is a book by American experimental composer John Cage (1912–1992), first published in 1961 by Wesleyan University Press. Silence is a collection of essays and lectures Cage wrote during the period from 1939 to 1961.

Most of the works are preceded by a short commentary on their origins, some have an afterword provided. Several works feature unorthodox methods of presentation and/or composition. "The Future of Music: Credo" juxtaposes paragraphs of two different texts. The text of the first part of "Composition as Process" is presented in four columns, the text of "Erik Satie" in two. "45' for a Speaker" is similar to Cage's "time length" compositions: it provides detailed instructions for the speaker as to exactly when a particular sentence or a phrase should be said. "Where Are We Going? and What Are We Doing?" is presented in several types of typeface to better reflect the concept of the lecture, which was originally presented as four tapes running simultaneously. "Indeterminacy" is a collection of various anecdotes and short stories taken from life or books Cage read: the concept is to tell one story per minute, and to achieve the speaker has to either speed up or slow down, depending on the length of the story.
