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.
