The New Haven Green is a public park and recreation area located in the downtown district of the city of New Haven, Connecticut. It comprises the central square of the original nine square settlement plan of the original Puritan colonists, and is bordered by the modern paved roads of College, Chapel, Church, and Elm streets.

Located on the green are three historic 17th century churches which reflect the city's theocratic roots.

• North Church, or the United Congregational Church is built in Federal style.
• Center Church, or The Congregational United Church of Christ established in 1639. The current church, designed in Georgian style by architect Ithiel Town, was built in 1812. Benedict Arnold's first wife is buried in its crypt, and regicide John Dixwell is buried behind the church.
• Trinity Church, which is an Episcopal congregation founded in 1752, was also designed by architect Ithiel Town, in Gothic Revival style. It was consecrated in 1816.

On the southeast side of the green, across Church Street, is New Haven's City Hall and adjacent Courthouse. On the northwest side of the green, across College Street, stands Phelps Gate , entryway into Yale University's Old Campus . On the northeast side along Elm Street is the New Haven Free Public Library , and on the southwest side along Chapel Street are stores, bars, and other commercial properties.

The green is also host to numerous public events, such as summer jazz and classical music concerts, as well as more mundane daily park activities.
