Saint John, Antigua and Barbuda

Saint John (Antiguan and Barbudan Creole: Sen Jan), officially the Parish of Saint John, is a civil parish of Antigua and Barbuda, on the northwestern portion of Antigua island. Its capital is the city of St. John's. Saint John borders Saint Mary, Saint Peter, Saint George, and Saint Paul. Saint John faces the Caribbean Sea. Saint John is surrounded by some of Antigua's most premier beaches. Saint John had a population of 56,736 in a 2018 estimate, making it home to the majority of the population in Antigua and Barbuda.

While Saint John is a civil administrative division, the Anglican parish church is located in the city of St. John's. Saint John is mostly centered around the St. John's urban area and the northern tourist area, but is also home to more rural areas in the southern salient and in the Five Islands-Yeptons area. Due to Saint John holding the majority of the population of Antigua and Barbuda, it is home to hundreds of populated locations some of which are vastly different from another. The island of Redonda is also under the administration of Saint John.

Saint John was created on 24 August 1681, when Antigua was divided into five parishes. Saint John and the four other parishes were permanently established in July 1692, and confirmed in January 1693. The primary objective of the establishment of parishes was providing for the parish church. Outside of the city, most of the rural areas of the parish were originally used as sugar mills. Many remnants of the parish's past are still visible in the modern day, such as with the Cedar Valley Plantation, or the Weatherill's plantation.
