Tappan is a hamlet and census-designated place in the town of Orangetown, Rockland County, New York, United States. It is located north of Old Tappan, New Jersey, east of Nauraushaun and Pearl River, south of Blauvelt, and west of Palisades and Sparkill. The population was 6,613 at the 2010 census.
The first Orange County courthouse was built in 1691 in Tappan, though by 1737, sessions alternated between Tappan and Goshen. The first school house in Rockland County was built in 1711 in Tappan. It was used as a school until 1860. There would not be another school in the county until late in the 18th century.
The Orangetown Resolutions were adopted in 1774 at the home and inn of Loyalist Yoast Mabie. The house was a Dutch colonial built by his cousin Casparus Mabie in Tappan when Great Britain increased its taxes on tea and crops, prompting protest from local patriots on Monday, July 4, 1774, two years to the date before the Declaration of Independence. Loyalist Yoast Mabie's home, known as "Mabie's Inn", was the place of confinement in 1780 of British Major John André, who plotted with American General Benedict Arnold to surrender West Point to the British. Today the house is a restaurant, operating daily as The Old 76 House.
General George Washington, who in 1789 became the first president of the United States, used the 1700 DeWint House, Rockland County's oldest existing structure in Tappan, as his headquarters four times between 1780 and 1783, and dined at Mabie's Inn during the American Revolution.
British Major John André, who conspired with Benedict Arnold to allow the takeover of West Point by the British, was captured in Tarrytown on his way back to the British lines with the plans of the fort's fortifications. Major André was brought to Tappan, confined at Mabie's Inn, and brought to trial at the Reformed Church of Tappan; he was found guilty of espionage, hanged, and buried nearby.
Strickland, Major André's executioner, who was confined at the camp in Tappan as a dangerous Tory during André's trial, was granted liberty for accepting the duty of hangman and returned to his home in the Ramapo Valley or Smith's Clove.
Joshua Hett Smith, accused of conspiring with Major André, was also brought to trial at the Reformed Church of Tappan. The trial lasted four weeks and ended in Smith's acquittal.
