Jabez Upham (August 23, 1764 – November 8, 1811) was a U.S. Representative from Massachusetts, a member of the Federalist Party, and part of a prominent New England political family. He was the brother of George Baxter Upham, a U.S. Representative from New Hampshire, and the cousin of Charles Wentworth Upham, who later served as a U.S. Representative from Massachusetts. Through his family line he was also the grandfather of Horace Gray, who became an Associate Justice of the Supreme Court of the United States.
Upham was born in Brookfield in the Province of Massachusetts Bay on August 23, 1764, during the colonial period preceding the American Revolution. Raised in a region that would become a center of early republican political life, he came of age as the colonies moved toward independence and the formation of the new nation. His early life in Brookfield placed him within the social and political milieu of rural Massachusetts, which would shape his later legal and political career.
He pursued higher education at Harvard University, then Harvard College, in Cambridge, Massachusetts, and graduated in 1785. Following his graduation, Upham studied law, a common path for educated men seeking public careers in the early republic. After completing his legal training, he was admitted to the bar and commenced the practice of law in Sturbridge, Massachusetts. His legal work in Sturbridge established his professional reputation and provided the foundation for his subsequent moves and political activity.
Seeking broader opportunities, Upham moved from Sturbridge to Claremont, New Hampshire, where he continued the practice of law. His time in New Hampshire connected him more closely with the branch of the Upham family that would produce his brother George Baxter Upham, also active in law and politics. Jabez Upham later returned to his native region, settling again in Brookfield, Massachusetts, where he resumed and maintained his legal practice. His standing as an attorney in Brookfield contributed to his emergence as a public figure in Massachusetts state politics.
Upham entered elective office as a member of the Massachusetts House of Representatives, serving from 1804 to 1806. In the state legislature he participated in the governance of Massachusetts during a period marked by the consolidation of Federalist and Democratic-Republican party structures and ongoing debates over the direction of the young republic. He returned to the Massachusetts House of Representatives again in 1811, reflecting the continued confidence of his constituents in his leadership and judgment.
At the national level, Upham was elected as a Federalist to the Tenth and Eleventh Congresses, representing Massachusetts in the U.S. House of Representatives. He served from March 4, 1807, until his resignation in 1810. His tenure in Congress coincided with a turbulent era in American politics, including rising tensions with Great Britain and France, controversies over trade restrictions, and the policies of the Jefferson and Madison administrations. As a Federalist, Upham aligned with a party that generally favored a strong national government, commercial interests, and closer economic ties with Britain, although specific details of his committee assignments and floor activity are not extensively documented in surviving records.
After leaving Congress in 1810, Upham returned to Massachusetts and continued his involvement in public affairs through his renewed service in the state legislature in 1811, while also maintaining his legal practice in Brookfield. His career reflected the pattern of early American public men who moved between state and national office and combined legal work with legislative service.
Jabez Upham died in Brookfield, Massachusetts, on November 8, 1811. He was interred in New Cemetery in West Brookfield, Massachusetts. His life and career, rooted in law, state politics, and national service, were part of a broader family tradition of public service that extended into the federal judiciary through his grandson, Supreme Court Justice Horace Gray.
