Theodorushaven is a harbour and industrial area located northwest of the city centre of Bergen op Zoom in the Netherlands, situated along the Volkerak-Zoommeer.

It forms part of the larger multimodal business district known as TNP, which also includes the adjacent areas of Noordland and De Poort. Together, the three zones host around 470 premises and approximately 110 active businesses.

The site plays a significant logistical role in the region, serving as a link in the supply chain between the ports of Antwerp and Rotterdam. Its multimodal connections make it an important economic driver for the municipality of Bergen op Zoom.
