Jacob Broom (July 25, 1808 – November 28, 1864) was an American Party member of the U.S. House of Representatives from Pennsylvania.

He was appointed deputy auditor of the State in 1840, and clerk of the Philadelphia Orphans’ Court from 1848 to 1852.

Broom presided over the party's national convention, which nominated Daniel Webster as its presidential candidate.

When Webster died nine days before the election, Broom was hurriedly named as his replacement, with Reynell Coates of New Jersey as his running mate.

He served as chairman of the House Committee on Revolutionary Pensions during the Thirty-fourth Congress.
