Isaac Knapp (January 11, 1804 – September 14, 1843)[2] was a printer and publisher in Boston, Massachusetts.


Knapp was born in Newburyport, Massachusetts to Philip Coombs Knapp and Abigail Remmick; siblings included Abigail Knapp.[3] In 1825 he was proprietor of the Essex Courant newspaper.[4][5]

With his friend William Lloyd Garrison he produced the anti-slavery Liberator newspaper, 1831-1841.[6][7] He also co-founded the New England Anti-Slavery Society.[8][9] His printing office was located on Congress Street (circa 1831) and then on Cornhill.[10][11]

Garrison and Knapp had a falling out around 1840, and Knapp left the Liberator. In an otherwise favorable eulogy written by Garrison and printed in the Liberator, Garrison implies Knapp became an alcoholic and that his death resulted from this.[12]
