Wilton's Dok- en Werf Maatschappij was a Dutch shipyard active as an independent company from 1854 till 1929. At first it was simply known as 'Wilton'. In 1921 the final Dutch name became: 'Wilton's Dok- en Werf Maatschappij NV', the equivalent of 'Wilton Engineering and Slipway Company'. Wilton started as a traditional smithy and expanded in machinery. It specialized in ship repairs, but also became a shipyard. At first only for fresh water ships. In spite of multiple name changes the company was commonly referred to as 'Wilton'. In 1929 a merger with Fijenoord led to a new company known as Wilton-Fijenoord.
