Seabrook is a city in the U.S. state of Texas within the Houston–Sugar Land–Baytown metropolitan area and Harris County. The population was 9,443 at the 2000 census and estimated to be 11,182 in 2006.
Seabrook is known for its fish markets on Waterfront Drive where resident shrimpers and fishermen bring in their catches daily. Besides bordering the bay, the city encompasses marshes though which runoff from inland fields drain to the bay. There are eight miles (13 km) of continuous trails from Hammer Street to Galveston Bay at Pine Gully Park, where the Lucky Trails Marathon is run in March. Seabrook is also host to the Texas Concours d'Elegance "Keels & Wheels" classic car and boat show held each year the first weekend in May at Lakewood Yacht Club.
The piece of land was purchased by Seabrook W. Sydnor in 1895. In March 1903, the Seabrook Company of Houston created a layout of the proposed Seabrook Town site. The new town attracted fishermen, merchants and even a few residents. The historic downtown that was built then still stands today, with many locals running their businesses. Most are antique shops of bed and breakfast places.
