Jacob Aaron Garber (born January 25, 1879) was a Republican member of the United States House of Representatives from Virginia. He represented Virginia’s 7th Congressional District and served a single term in Congress. His tenure in the U.S. House began on April 15, 1929, and concluded on March 3, 1931.

Garber held the office of Representative as a historical member of Congress during this brief period, aligning with the Republican Party at a time when Virginia politics were largely dominated by Democrats. Serving one term, from 1929 to 1931, he is recorded as a former officeholder with no additional committee assignments, official contact details, or subsequent federal roles noted in the available record.
