The Liberator was an abolitionist newspaper founded in 1831 by William Lloyd Garrison. It only had a circulation of about 3,000, but still earned nationwide notoriety for Garrison, who used The Liberator to advocate "immediate and complete emancipation of all slaves" in the United States.

The Liberator was published until 1865 when the American Civil War came to a close and the 13th Amendment abolished slavery in all the states.
