Tonwaren-Industrie Wiesloch (TIW AG, originally Thonwaaren-Industrie Wiesloch GmbH, abbreviated Ton) was a brickworks which existed in Wiesloch, Germany between 1895 and 1989. It was one of the largest and most significant factories in Germany. The factory was located just north of Wiesloch-Walldorf station and was the largest employer in Wiesloch.

Raw clay material was excavated from a clay pit in the Dämmelwald forest on the north-west side of Wiesloch. This clay material was located at an elevation of 120 metres above sea level within the Upper Rhine Graben.

The factory contained one of many industrial 600 mm gauge railways in Germany. Use of the narrow-gauge trains to fetch material from the clay pit finished in 1979. Since 2001 the Wiesloch Feldbahn and Industrial Museum has been based at part of the north end of the site, and since 2016 the Leimbach Park has been built on the south end of the site, with the rest of the area transformed into an industrial zone.
