Jacob Miller Campbell (born November 20, 1821) was a Republican member of the United States House of Representatives from Pennsylvania. He represented Pennsylvania’s 17th congressional district and served as a federal legislator during the late nineteenth century. Campbell’s service in Congress places him among the historical members who helped shape national policy during the post–Civil War and Reconstruction-era aftermath.

Campbell served as a Representative from October 15, 1877, to March 3, 1887, completing four terms in office. During this decade in the House of Representatives, he was aligned with the Republican Party and represented the interests of his Pennsylvania district at the federal level. Although specific committee assignments, legislative initiatives, and additional biographical details are not provided in the available record, his tenure from 1877 to 1887 marks him as a significant political figure for Pennsylvania’s 17th district in that period.
