Port Jefferson is located at (40.946103, -73.062224), on the North Shore of Long Island, about 56 miles east of New York City. The Bridgeport and Port Jefferson Ferry company operates three vessels that make daily runs from Port Jefferson across Long Island Sound to Bridgeport, Connecticut. The three vessels are the 'Grand Republic' (built in 2003), the 'P.T. Barnum' (built in 1999) and the 'Park City'(built in 1988).
According to the United States Census Bureau, the village has a total area of 3.0 square miles (7.9 km²), of which, 3.0 square miles (7.8 km²) of it is land and 0.04 square miles (0.1 km²) of it (0.98%) is water.
One notable geographic feature is Pirate's Cove, a small cove dredged long ago by the Seaboard Dredging Company. The original name was Seaboard Hole, but it was changed for the sake of appealing to tourists. Several large sand dunes (artificially created by the dredging) are found here.
Port Jefferson is not to be confused with the Hamlet of Port Jefferson Station south of the train tracks.
Port Jefferson at one time was a small ship building community, with the name Drowned Meadow. The community leaders, realizing this was a poor name for the ship building business, eventually changed its name to Port Jefferson after President Thomas Jefferson. The town was once a major whaling port, especially in the 1880s.
The Village was named after Jefferson because he was the major source of funding for a project to prevent the flooding of the lower village from whence the original name originated -- Drowned Meadow.
P.T. Barnum, the famous circus owner, owned a tract of land which ran through the village. His intention was to make Port Jefferson the home base for his circus. The townspeople put a stop to his plans, and he eventually sold his land. A street named "Barnum Ave." now runs though the area that was once his land, and a house he had constructed still exists, in private hands.
The Village of Port Jefferson was incorporated in 1964.

Port Jefferson is home to an annual Charles Dickens Festival, since the early 1990s, early in December. This typically includes many events and occurrences, such as the regular sighting of people who dress in 19th century clothing, house tours, the reading of winter-related poetry, caroling, and booths set up by local businesses. Students from the Port Jefferson Middle School and High School submit poetry and art that are used in the festival. Free concerts of seasonal music by various ensembles are presented at the Methodist church.
As well as this festival, many small festivals are held during the summer, showcasing music and crafts. Each Fourth of July sees a substantial parade on Main Street.
The Port Jefferson School District also has an agreement with Comsewogue School District to send its upper port students to Comsewogue Schools.
