Mastic Beach is a waterfront hamlet located in the Town of Brookhaven, Suffolk County, on Long Island’s South Shore. Known for its stunning views of the Great South Bay, its proximity to Fire Island, and its relaxed coastal charm, Mastic Beach offers residents and visitors a true taste of Long Island’s maritime heritage. Once incorporated as a village between 2010 and 2017, it remains a tight-knit, scenic community where boating, fishing, and bayfront living define daily life.

A Coastal Community with Character

Mastic Beach sits along the Forge River and Moriches Bay, making it one of Long Island’s most naturally beautiful settings. The area’s geography provides abundant access to waterways, marinas, and nature preserves, including the William Floyd Estate-a National Park Service site that was home to one of the original signers of the Declaration of Independence.

The community features a mix of bayfront homes, cottages, and modest suburban houses, all surrounded by salt marshes, creeks, and coastal wetlands. While still residential in character, Mastic Beach also has small local businesses, eateries, and fishing supply stores that cater to outdoor enthusiasts and year-round residents alike.

Nature and Recreation

Just minutes away, Smith Point County Park offers one of the South Shore’s most popular beaches, campgrounds, and boardwalks leading to the Fire Island National Seashore. Kayaking, paddleboarding, and birdwatching are favorite activities among locals. The nearby Poospatuck Reservation, home to the Unkechaug Nation, adds cultural depth and historical significance to the area.
