Hitachi Shipbuilding Corporation (日立造船, Hitachi Zōsen^?) is a major Japanese industrial and engineering corporation. It produces waste treatment plants, industrial plants, precision machinery, industrial machinery, steel mill process equipment, steel structures, construction machinery, tunneling machines, and power plants. Despite its name, Hitachi Shipbuilding no longer builds ships, having spun this business off in 2002.

Hitachi Zōsen's origins go back to April 1, 1881, when British entrepreneur Edward H Hunter established Osaka Iron Works (大阪鉄工所, Ōsaka Tekkosho^?) in Osaka to develop the Japanese steel-making and shipbuilding industry. Hunter had come to Japan in 1865 and had established the Onohama Shipyard in Kobe before moving to Osaka and establishing a new shipyard at the junction of the Nakatsu and Aki rivers which could construct ships of under 1000 tons displacement. His first vessel, the Hatsumaru was launched in 1882. Hunter intended to build a company which was completely self-sufficient, and also produced engines, boilers, bridges and irrigation equipment.
