An American Life is the 1990 autobiography authored by former American President Ronald Reagan. Released almost two years after President Reagan left office, the book reached number eight on The New York Times' bestsellers list.

The book is composed of 748 pages, describing Reagan's life from his birth in Tampico, Illinois, to his acting career, marriages, entrance into politics, years as Governor of California, loss in the 1976 Republican primary, and finally his years as President of the United States. Reviewer John O'Sullivan says of Reagan, "[H]e shows a tendency, where other people's feelings are concerned, to gloss over unpleasantness in a way which does him credit as a Christian, but detracts somewhat from his value as a historian." He revealed the events that led to his reluctant 1976 candidacy, as well as his relationships with members of Congress and his views on the world and the Cold War.

Ronald Wilson Reagan was the 40th President of the United States (1981–1989) and the 33rd Governor of California (1967–1975).

Born in Tampico, Illinois, raised in Dixon, Illinois, and educated at Eureka College with a bachelor of arts degree in economics-sociology, Reagan first moved to Iowa as a radio broadcaster and then to Los Angeles, California in 1937. He began a career as an actor, first in films and later television, appearing in over 50 movie productions and gaining enough success to become a famous, publicly recognized figure. Some of his most notable roles are in Knute Rockne, All American and Kings Row. Reagan served as president of the Screen Actors Guild, and later spokesman for General Electric (GE); his start in politics occurred during his work for GE. Originally a member of the Democratic Party, he switched to the Republican Party in 1962. After delivering a rousing speech in support of Barry Goldwater's presidential candidacy in 1964, he was persuaded to seek the California governorship, winning two years later and again in 1970. He was defeated in his run for the Republican presidential nomination in 1968 as well as 1976, but won both the nomination and election in 1980.
