America Day by Day

America Day by Day is a 1948 book by Simone de Beauvoir chronicling her trip by road across the United States of America over four months in 1947. It was published in French in 1948 with an English translation in 1953. A new translation in English by Carol Cosman with a foreword by Douglas Brinkley was published in 1999 by the University of California Press.

The book grew from the essay "An Existentialist Looks at Americans", published in The New York Times Magazine in 1947.
