Peter Dumont Vroom (December 12, 1791 – November 18, 1873), an American Democratic Party politician, served as the ninth governor of New Jersey (serving two terms in office; from 1829–1832 and 1833–1836) and as a member of the United States House of Representatives for a single term, from 1839 to 1841.

He was born in Hillsborough Township, New Jersey, the son of Col. Peter Dumont Vroom who represented Somerset County as an Assemblyman (1790–91, 1794–96, and 1811–13) and in the Legislative Council from 1798 to 1804 as a Federalist.

As governor, Vroom supported the establishment of the Camden and Amboy Railroad and the Delaware and Raritan Canal.

Disputed election results caused the U.S. House of Representatives to challenge the Whig candidates certified by Governor William Pennington.

He was appointed by President Franklin Pierce as United States Minister to Prussia from November 4, 1853, through August 10, 1857.
