Bethlehem Beaumont Shipyard was a shipyard in Beaumont, Texas that opened in 1948. The yard is located on an island in the Neches River and upstream of the Sabine Pass that grants access to the Gulf of Mexico. The deep-water port shipyard was founded in 1917 as the Beaumont Shipbuilding & Dry Dock Company. Beaumont Shipbuilding & Dry Dock Company started as a World War I Emergency Shipbuilding Program yard.

In 1922 the Pennsylvania Car & Foundry, of Sharon, Pennsylvania purchased the yard and renamed the yard Pennsylvania Shipyards, Inc.. The yard built barges and rail cars and also operated under the name Petroleum Iron Works at the site. For World War II the yard build tugboats and barges as part of the emergency shipbuilding program. After the war Bethlehem Steel purchased the yard in 1948 as part for the Bethlehem Shipbuilding Corporation. Bethlehem Beaumont Shipyard transitioned the yard into a jackup rig offshore drilling rig yard.

The yard closed in the 1980s, with the rig market collapse. Bethlehem Steel sold the yard in 1989 to Trinity Industries. Trinity Industries purchased a Panamax floating drydock and continued operations. The drydock was moved to New Orleans in 1994. Chicago Bridge & Iron Company purchased the yard in 2006. Chicago Bridge & Iron turned the yard into a fabrication yard. In 2017 Chicago Bridge & Iron Company closed the yard due to damage from Hurricane Harvey, ending work for 455 employees. Many of workers were relocated to other Chicago Bridge & Iron sites. The site is now Allegiant Industrial Island Park Campus that opened in 2018.

In the interwar period the yard built over 200 vessels, mostly for companies in the oil business, with Texaco being the biggest customer by number of ships. The Texas oil boom could conceivably have to do something with this unusually high activity at a time when shipbuilding in the rest of the country was at a low point due to the surplus produced in the World War I boom years. The first war related work came in the form of two C1-A cargo vessels for the Maritime Commission. Apart from 4 minesweepers for the Navy and a handful of ships for private businesses, Pennsylvania produced primarily for the merchant marine with C1-A and C1-M ships the most numerous types of ships built.

Chicago Bridge & Iron Company Beaumont (1982-2017) closed the Beaumont yard, called Beaumont Island Park Fabrication Services, in 2017, after the site was flooded due to Hurricane Harvey in September 2017. The sited had fabricated and transport large-scale process modules, shop-built ships and large steel plate subassemblies since 1982. In 2008 Chicago Bridge & Iron Company sold the site to Port of Beaumont. Port of Beaumont entered into a partnership with Allegiant Industrial to rebuild the 75 acres site.

Allegiant Industrial opened the Allegiant Industrial Island Park Campus (2018- ) on the site in October 2018. The site has 500,000 square feet of welding, painting and fabrication space.
