West Point is the oldest continuously occupied military post in the United States. Located on the Hudson River in New York, General George Washington stationed his headquarters in West Point in the summer and fall of 1779 during the American Revolutionary War, and later called it "the most important Post in America" in 1781 following the war's end. West Point was also the site of General Benedict Arnold's failed attempt at treason during the Revolutionary War.

West Point was first occupied by the United States Armed Forces in January 1778 by Brigadier General Samuel Holden Parsons. Since then, West Point has been occupied by the United States Army. It comprises 25.1 sq mi (65 km²) land and water, including the campus of the United States Military Academy, which is commonly referred to as "West Point".

West Point is a census-designated place (CDP) located in the town of Highlands in Orange County, located on the western bank of the Hudson River. The population was 7,341 at the 2020 census. It is part of the Kiryas Joel–Poughkeepsie–Newburgh metropolitan area as well as the larger New York–Newark, NY–NJ–CT–PA Combined Statistical Area.

The site for West Point was originally picked because of the pronounced S-curve in the Hudson River at that point during the American Revolutionary War, and was the subject of a committee reporting on fortifications in the Hudson River in November 1775, which first recommended occupying the land. Construction of the fort was begun under Captain Louis de la Radiere as chief engineer of the fort, however, New York Governor George Clinton thought that Radiere was "lacking" in the knowledge needed to hold his position. Thus it was completed under Polish Colonel Tadeusz Kościuszko between 1778–1780; it was a key defensive fortification, overlooking the turn in the Hudson River and the Great Chain. On January 27, 1778, Brigadier General Samuel Holden Parsons and his brigade, including elements of Connecticut Colony's patriot militia, crossed an iced over Hudson River and climbed to the plain on West Point.

General George Washington watched the construction of the fort closely and considered the fort to be General Alexander McDougall's "first priority".

In 1778, Major General Israel Putnam wrote, "The place agreed upon to obstruct the navigation of Hudson river was at West Point." A fort there, Fort Clinton, named after the governor's brother, Colonel James Clinton (whose brigade built the main fort), was built as well. The southern and western walls were nine feet high and twenty feet thick. Three redoubts and batteries on the south were named Forts Meigs, Wyllys, and Webb.

West Point was staffed by a small garrison of Continental Army Soldiers from early in 1776 through the end of the war. A great iron chain was laid across the Hudson at this point in 1778 to prevent British Navy vessels from sailing further up the Hudson River, which was never tested by the British. The site comprised multiple redoubts, as well as Fort Putnam, situated on a high hill overlooking the river. Named after its builder, Revolutionary War General and engineer Rufus Putnam, the fort is still preserved in its original design.

Parliament sent instructions to General Sir Henry Clinton to force George Washington out of West Point. Clinton decided to capture the strategically important posts Stony Point and Verplanck's Point, which were twelve miles south of West Point. Clinton captured the forts on June 1, 1779. To block the British advance, Washington moved his troops further up the Hudson.
