Brookhaven is a really big suburban town in Suffolk County, Long Island, New York. It's one of the largest towns in the United States by population. In 2022, about 488,497 people lived here. This makes it the second most populated town in New York State.
The first settlement in Brookhaven was called Setauket. It started as small farming communities in the mid-1600s. Later, in the 1800s, Brookhaven became a major center for building ships. Because it's close to New York City, it became a popular place for vacation resorts. After World War II, many more people moved here, causing a big population increase.
Brookhaven is home to two famous research centers: Stony Brook University and Brookhaven National Laboratory. These two places employ a lot of people in the town. Tourism is also a big part of the local economy. You can find busy downtown areas in Port Jefferson and Patchogue. Port Jefferson is a hub for the Bridgeport & Port Jefferson Ferry. The Long Island Rail Road has served the area for a long time.

History
How Brookhaven Started
The first people known to live here were Native Americans. They spoke Algonquian languages and belonged to the Setauket and Unkechaug tribes. English settlers arrived around 1640. In 1655, some settlers bought land from these tribes. This year, 1655, is now recognized as the founding year of Brookhaven. It was when the first land deal happened in Setauket.
This makes Brookhaven the fifth English town founded on Long Island. Before it were Southampton, Southold, Huntington, and East Hampton.

The first English settlement was named "Setauket" after the local Native American tribe. For a while, "Brookhaven" and "Setauket" were used for both the village and the larger town. It wasn't until the 1800s that Setauket became just a smaller area within the town of Brookhaven. There's even a hamlet today called Brookhaven, which was named after the larger township in 1879.
The first land purchase in 1655 included areas like Setauket, Stony Brook, and Port Jefferson. In 1664, Richard Woodhull bought more land. This expanded the town eastward along the North Shore. It included places like Mount Sinai, Miller Place, and Wading River.
Brookhaven became part of the Province of New York in 1664. In 1666, Governor Richard Nicolls gave the town a special document called a patent. This confirmed their ownership of the land. Later, in 1686, Governor Thomas Dongan issued another patent. This one gave the town more powers and set up a local government. The town's official seal was also created then. The letter "D" on the seal was the town's official cattle earmark from 1665. The olive branch on the seal likely meant peace, and the whaling tools showed that whaling was a very important business back then. Today's seal is a new design, but it still has these original symbols and the 1655 founding date.
Life in Colonial Times
Early English settlers in Brookhaven were mostly farmers, fishers, and whale hunters. The town was very rural, with only a few families in each area, but miles of land. Fishing helped the economy in coastal areas. A big shopping or business center didn't really exist until the early 1800s.
Brookhaven was first settled by English colonists who came from Southold. It was first under the control of the New Haven Colony in Connecticut. In 1662, it moved to the Connecticut Colony. Then, in 1664, England took over New Netherland, and Brookhaven became part of the new colony of New York.
The American Revolutionary War
During the American Revolutionary War, British forces took control of Long Island, including Brookhaven. Many residents supported the British. However, Brookhaven also saw brave actions by Americans during the war.
One famous group was the Culper Spy Ring. These spies worked for George Washington. Many of them were from Brookhaven and operated in areas controlled by the British. Another event was Benjamin Tallmadge's daring raid. He and his team rowed from Connecticut to Cedar Beach. They then marched across Long Island to attack the British fort at Manor St. George. This led to the Battle of Fort St. George and the burning of the fort. There was also a smaller fight in Setauket. The British had turned the local church into a fort. You can still see some bullet holes in the walls of the nearby Caroline Church.
Growing Up: From Ships to Science
In the mid-1800s, some Brookhaven communities became busy shipbuilding ports. Port Jefferson and Patchogue were the most successful. They are still the town's busiest downtown areas today. Whaling and cutting wood for fuel also became important industries.
Railroads arrived in Brookhaven in the mid-1800s. Trains first reached Ronkonkoma in 1843. The Port Jefferson Branch on the North Shore started running in 1873. The Bridgeport & Port Jefferson Ferry has been carrying cars and people between Port Jefferson and Bridgeport, Connecticut, since 1888. Even the famous circus owner P.T. Barnum helped start it!
From the late 1800s to the mid-1900s, many towns along the North and South Shores became popular resort spots. People from New York City, including famous celebrities, would come here for summer vacations. Many rural parts of Brookhaven were used as campgrounds for youth groups.
During the Gilded Age, wealthy people built fancy homes along the North Shore. Places like Belle Terre and Old Field changed from small fishing villages into exclusive neighborhoods for the rich.
Important scientific research also happened in Brookhaven around the early 1900s. Inventor Nikola Tesla had a research center in Shoreham. It featured the huge Wardenclyffe Tower. Today, this site is being turned into the Tesla Science Center at Wardenclyffe. Guglielmo Marconi opened one of the world's largest radio facilities, called Radio Central, in Rocky Point.
Modern Brookhaven
After World War II, Brookhaven's population grew a lot. This was partly because it was easy to get to New York City by the Long Island Rail Road and highways. The town's most famous institutions, Stony Brook University and Brookhaven National Lab, were both started after the war.
In the mid-1900s, a kind person named Ward Melville made big changes in the "Three Village" area. This includes The Setaukets, Stony Brook, and Old Field. Melville, who lived in Old Field and owned what became CVS, used his money to make Northwestern Brookhaven look like an ideal New England town. In 1939, he built the Stony Brook Village Center. It's a pretty shopping area in Stony Brook, with buildings designed to look old and colonial. In 1962, Ward Melville gave 400 acres of land for Stony Brook University to move there.
Brookhaven National Laboratory (BNL) is built on the site of Camp Upton. This was a United States Army training camp during World War I and World War II. Thousands of soldiers, including composer Irving Berlin, trained there. In 1946, the land was given to the new national laboratory, which opened the next year. Brookhaven researchers have done amazing things. They patented Maglev trains, designed one of the first video games, found the first solar neutrinos, and created the first PET scan. They also made many discoveries in particle physics. The lab has the Relativistic Heavy Ion Collider (RHIC) and the National Synchrotron Light Source. A famous physicist named I.I. Rabi helped a lot to create the lab.
Geography
Brookhaven is in the middle of Long Island. It stretches from the North Shore to the South Shore. It's the largest town in New York by total area, including water. However, some towns have more land area.
Brookhaven is bordered by Long Island Sound to the north and the Atlantic Ocean to the south. It also shares borders with other towns like Riverhead, Southampton, Smithtown, and Islip.
A big part of Fire Island is in Brookhaven. You can reach it by a bridge at Smith Point. The Great South Bay is also part of the town.
Bald Hill in Farmingville is a large hill. It marks where the glacier that formed Long Island stopped long ago. At the top, there's a memorial for Vietnam veterans. Telescope Hill, west of Bald Hill, is slightly taller. It's the highest point in the town.
