Leonard Andrew Grimes (November 9, 1815 – March 14, 1873) was an African-American abolitionist and pastor.
He served as a conductor of the Underground Railroad, including his efforts to free fugitive slave Anthony Burns captured in accordance with the Fugitive Slave Act of 1850.
After the Civil War began, Grimes petitioned for African-American enlistment.
He then recruited soldiers for the 54th Regiment Massachusetts Volunteer Infantry.
