John Page, Jr. was born in Haverhill, New Hampshire on May 21, 1787, the son of John Page and Hannah Rice Green. He attended the local schools and became a farmer. During the War of 1812 Page served as lieutenant in a local militia company which performed duty on the border with Canada to prevent contraband trade and deter the threat of a British invasion. While the war was ongoing and immediately afterwards Page held the federal office of tax assessor. Page's party affiliation remained with different facets of the Democratic Party, and moved over time from the Democratic-Republican Party to the Jacksonians to the Democrats to the Free Soil Party. He was a member of the New Hampshire House of Representatives from 1818 to 1820. Page was also a longtime local and county official, serving as Register of Deeds for Grafton County in 1827 and again from 1829 to 1835.

Page served from June 8, 1836, to March 3, 1837. During the 1836 election to fill the vacancy it was agreed between the candidates that Page would complete Hill's term and then defer to Franklin Pierce. In 1837 Pierce was elected to a full six-year term and succeeded Page. During his Senate service Page was chairman of the Committee on Agriculture. In 1839 Page was elected governor as a Democrat.
