Levi Woodbury (December 22, 1789 – September 4, 1851) was an Associate Justice of the Supreme Court of the United States, a U.S. Senator, Governor of New Hampshire and cabinet member in three administrations. He was the first Justice to have attended law school.

Woodbury was born in Francestown, New Hampshire. He graduated from Dartmouth College, Phi Beta Kappa, in 1809, briefly attended Tapping Reeve Law School in Litchfield, Connecticut, and read law to be admitted to the New Hampshire Bar in 1812. He was in private practice in Francestown from 1812 to 1816. He also joined the Freemasons.

Woodbury was a clerk of the New Hampshire State Senate from 1816 to 1817, and a Justice of New Hampshire state supreme court from 1817 to 1823. He was Governor of New Hampshire from 1823 to 1824 and was Speaker of the New Hampshire State House of Representatives, 1825.

Woodbury served as a United States Senator from New Hampshire from 1825 to 1831. Elected to serve in New Hampshire state Senate in 1831, Woodbury did not take office due to his appointment as United States Secretary of the Navy under President Andrew Jackson, from 1831 to 1834. At the beginning of this term, he was instrumental in the appointment of fellow New Hampshireman Edmund Roberts as special agent and envoy to the Far East. Woodbury served as Secretary of the Treasury under Jackson and Martin Van Buren from 1834 to 1841, and served again as Senator from New Hampshire from 1841 to 1845. He was a Justice of the U.S. Supreme Court, 1845 to 1851.
