Abby Kelley Foster (January 15, 1811 – January 14, 1887) was an American abolitionist and radical social reformer active from the 1830s to 1870s. She became a fundraiser, lecturer and committee organizer for the influential American Anti-Slavery Society, where she worked closely with William Lloyd Garrison and other radicals. She married fellow abolitionist and lecturer Stephen Symonds Foster, and they both worked for equal rights for women.

Her former home of Liberty Farm in Worcester, Massachusetts has been designated a National Historic Landmark.
