Philip F. Spaulding (1912–2005) was a naval architect who lived and worked in Seattle, Washington.
He played an immense role in shaping North America's ferries for more than half a century, and he also designed many yachts along the way.
In 1952 he founded the marine design firm Philip F. Spaulding and Associates, which he led until his retirement in 1980.
Spaulding was commissioned to design many ferries and other ships used on North America's West coast.
In 1987, many years after a merger and name change to Nickum and Spaulding Associates, the company was renamed Elliott Bay Design Group and its assets were sold to its employees.
