Jacob Joseph Pugsley (born January 25, 1838) was a Republican politician who represented the state of Ohio in the United States House of Representatives in the late nineteenth century. Serving as a member of Congress from Ohio’s 12th Congressional District, he held federal office during a period of significant political and economic change in the post–Civil War era.

Pugsley served two terms in the U.S. House of Representatives, holding the role of Representative from December 5, 1887, to March 3, 1891. During this time, he was a historical member of Congress identified with the Republican Party, reflecting the party’s dominance in many northern states in the decades following the Civil War. His service in Congress marked his principal known contribution to public life at the national level.

After March 3, 1891, Pugsley left office and is recorded as a former member of Congress. While specific committee assignments, legislative initiatives, or subsequent public roles are not detailed in the available information, his tenure as Representative for Ohio’s 12th District from 1887 to 1891 situates him among the cohort of late nineteenth-century lawmakers who helped shape federal policy during that era.
