Orange is a city in and the county seat of Orange County, Texas, set on the Sabine River at the Louisiana state line. It is the easternmost city in Texas, located about 113 miles east of Houston and part of the Beaumont–Port Arthur metropolitan area, an industrial region often called the Golden Triangle. With a population of roughly 19,000, Orange combines the role of a small Southeast Texas county seat with the economic weight of a deepwater port. The city's history is built on the Sabine River. The settlement was known as Green Bluff in its early years, then Madison, before taking the name Orange in 1858. In the late 19th century, the city's many sawmills made it a center of the Texas lumber industry. During the mid-20th century, shipbuilding boomed along the river, and the postwar decades brought petrochemical plants and steel facilities that solidified Orange's place in the Golden Triangle's industrial economy. The canalized Sabine River connects the city to the Gulf Intracoastal Waterway, and the Rainbow Bridge, completed in 1938, links Orange with Beaumont and Port Arthur. Modern Orange is a compact city with a historic riverfront, a working port, and Interstate 10 running through it, carrying tens of thousands of vehicles a day between Texas and Louisiana. The Lutcher Theater and the Riverfront Boardwalk anchor the city's cultural and recreational life, while Lamar State College Orange brings higher education to the area. The city's role as a county seat adds government employment and services to an economy long defined by manufacturing and shipping. For households, Orange offers a small-city pace of life within reach of larger regional centers. Its school options span several districts, including Orangefield ISD, West Orange-Cove CISD, and Little Cypress-Mauriceville CISD, and its neighborhoods range from historic streets near the river to newer subdivisions with waterfront settings. Orange suits those who want an affordable, history-rich base in Southeast Texas with direct highway access to Beaumont, Port Arthur, and the Louisiana border.
