George Washington's reception at Trenton is hosted by the Ladies of Trenton as he journeys to New York City for his first inauguration.

George Washington's reception at Trenton was a celebration hosted by the Ladies of Trenton social club on April 21, 1789, in Trenton, New Jersey, as George Washington, then president-elect, journeyed from his home at Mount Vernon to his first inauguration in the then capital of the United States, New York City. A ceremonial triumphal arch was erected on the bridge over the Assunpink Creek to commemorate his two victories here, the Battle of Trenton on December 26, 1776 and the Battle of the Assunpink Creek on January 2, 1777.

The first inauguration of George Washington as the first president of the United States was held on Thursday, April 30, 1789, on the balcony of Federal Hall in New York City. The inauguration was held nearly two months after the beginning of the first four-year term of George Washington as president. Chancellor of New York Robert Livingston administered the presidential oath of office. With this inauguration, the executive branch of the United States government officially began operations under the new frame of government established by the 1787 Constitution. The inauguration of John Adams as vice president was on April 21, 1789, when he assumed his duties as presiding officer of the United States Senate; this also remains the only scheduled inauguration to take place on a day that was neither January nor March.

April 21 is the 111th day of the year in the Gregorian calendar; 254 days remain until the end of the year.
