John Greene (died 16 June 1883) was an Irish landowner and politician from County Kilkenny.
At the 1847 general election, Greene was elected to the United Kingdom House of Commons in Westminster as one of the two Members of Parliament (MPs) for the County Kilkenny constituency. He was re-elected at the next three general elections, and held the seat until his defeat at the 1865 general election by George Leopold Bryan. He was first elected as Repeal Association candidate, and thereafter as a Liberal Independent (1852), a member of the Independent Irish Party in 1857, and as a Liberal in 1859 and at his defeat in 1865.

John Greene (fl. 1862) was a Union Navy sailor in the American Civil War and a recipient of the U.S. military's highest decoration, the Medal of Honor, for his actions at the Battle of Forts Jackson and St. Philip.
Greene joined the Navy from New York and served during the Civil War as a captain of the forecastle on the USS Varuna. At the Battle of Forts Jackson and St. Philip near New Orleans on April 24, 1862, Varuna was rammed twice by the Confederate steamer CSS Governor Moore (formerly known as the Charles Morgan) and eventually sunk. Greene acted as a gun captain and "remained steadfast at his gun throughout the thickest of the fight and was instrumental in inflicting damage on the enemy". For this action, he was awarded the Medal of Honor a year later, on April 3, 1863.
Greene's official Medal of Honor citation reads:
John Greene (c.1594–1658) was an early settler of the Colony of Rhode Island and Providence Plantations, one of the 12 original proprietors of Providence, and a co-founder of the town of Warwick in the colony. Sailing from England with his family in 1635, he first settled in Salem in the Massachusetts Bay Colony, but had difficulty with the Puritan authority, and soon followed Roger Williams to Providence, becoming one of the original proprietors of that town. In 1643 he joined Samuel Gorton and ten others in purchasing land that would become the town of Warwick. Difficulties with Massachusetts ensued, until he accompanied Gorton on a trip to England where they secured royal recognition of their town.
Once Warwick became safe from external threats, Greene became active in its government, serving on the town council, being Deputy to the General Court of the colony, and serving as magistrate of the General Court of Trials. He died in the last days of 1658, being survived by his wife and six grown children, and becoming the ancestor of many prominent citizens.
