John Pierce St. John (February 25, 1833 - August 31, 1916) was an American politician during the 19th century. Born in Brookville, Indiana, he served as a colonel in the Union Army during the American Civil War.

St. John served in the Kansas State Senate in 1873 and was the Republican Governor of Kansas from 1879 to 1883. Active in the temperance movement, he successfully promoted a prohibition amendment to that state's constitution. He was the Prohibition Party candidate for President of the United States in the 1884 election. He received 147,482 votes (about 1.5%) on a ticket with William Daniel.

Election was won by Stephen Grover Cleveland of the Democratic Party. St. John was also surpassed by two other unsuccessful candidates:

• James Gillespie Blaine of the Republican Party.
• Benjamin Franklin Butler of the United States Greenback Party. St John died in 1916 in Olathe, Kansas.
