The Okhta shipyard was a Russian shipyard based in Saint Petersburg. It was located in the district Russian Empire. at the confluence of the Okhta and Neva rivers. Shipbuilding history in the area goes back to 1721, when Okhta was settled and the residents processed wood for shipbuilding. In 1807 the land was purchased by the Russian navy and became the site of the Okhta Admiralty yard. The first vessel was built in 1811, under supervision of a nearby institute. Since the beginning the main customer was the Russian Admiralty. During the years 1811–1864 the Okhta yard built more than 160 vessels, including nine ships of the line, and was the most important yard of the Imperial Russian Navy during this period. By the 1860s, when steel hulls replaced wood, the yard became outdated.
