Jonathan Chapman (January 23, 1807 – May 25, 1848) was an American politician who served as the eighth mayor of Boston, Massachusetts from 1840 to 1842.

[6] Chapman attended Phillips Exeter Academy, graduated from Harvard College, and studied law under the direction of Judge Lemuel Shaw.

Because Suffolk County was constructing a new building for the Registry and Probate offices and was going to move out of the old courthouse building, Chapman instead recommended that the old Suffolk County Courthouse be remodeled for use as Boston's city hall.

[2] Chapman spoke of the great importance of the establishment of the Cunard Lines[2] steamship[8] service between Boston and Liverpool, England.

Chapman also spoke of the great importance of the opening up of the Western Railroad from Boston to the Hudson River.
