Ets Foidart et Rosenthal was a Belgian automobile manufacturer based in Brussels, established in the year 1900. The company made its debut at the 1900 Brussels Show, where it showcased two models of automobiles featuring single-cylinder horizontal engines. These vehicles were rated at 3 and 7 horsepower and were equipped with 3-speed gearboxes.

Despite the initial exhibition, there was little subsequent development of these models. In 1914, Foidart et Rosenthal announced plans to produce a steam wagon; however, the onset of World War I hindered the realization of this project, leading to the company's eventual decline. The firm remains a lesser-known entity in the early history of the automotive industry in Belgium.
