Lucy Delaney (c. 1830 – after 1891) was an African-American author and former slave, remembered for her inspiring 1891 narrative From the Darkness Cometh the Light, or, Struggles for Freedom. The memoir recounts her mother Polly Berry's struggle for her own and her daughter's freedom from slavery, as she was freeborn. Berry won both of these cases in the early 1840s, gaining active support from Edward Bates, a prominent Whig politician.
