James Ware Bradbury (born June 10, 1802) was a Democratic United States senator from the state of Maine. He served a single term in the U.S. Senate from December 6, 1847, to March 3, 1853, representing Maine at the federal level during the mid-nineteenth century. His tenure in office places him among the historical members of Congress from that period.

During his time in the Senate, Bradbury served as a senator for Maine without a designated district, as U.S. senators represent their states at large. He completed one full term before leaving office in 1853. Beyond his party affiliation, dates of service, and role as a senator, no additional official positions, committee assignments, or contact details are recorded in the available metadata.
