Robert Emanuel Mattson (16 May 1851 – 10 May 1935) was a Finnish shipowner and businessman. Mattson was born in Åland to a shipowner family. He went to sea at young age and studied shipmaster degree. After ten years at sea he settled in Mariehamn and started trading; soon he went into shipping business. Mattson operated solely old sailing ships, which were often lost due to their poor condition. However, the business was profitable. In the 1920s Mattson changed to steam ships but could not operate them successfully.
