The Seattle Construction and Drydock Company was a shipbuilding company based in Seattle, Washington. Between 1911 and 1918, it produced a substantial number of ships for both commercial and military uses. In the beginning of the 20th century, until its significance was diluted by the emergence of a number of shipyards during the World War I shipbuilding boom, it was the largest of its kind in Seattle and one of the few significant ship yards along the West Coast of the United States, second only to the Union Iron Works in San Francisco.

Robert Moran was a Seattle shipbuilder who served as the city's mayor from 1888 to 1890. Today he is primarily remembered for Moran Brothers Co. shipbuilders, his work as mayor to rebuild after the Great Seattle fire, and his large estate on Orcas Island, which became a resort and Moran State Park.
