Helmstedtisuchus is an extinct genus of fish. Fossils have been found from Helmstedt, Germany that are late Eocene in age.Schleich, H. H., Vahldiek, B. W., Karl, H. V. and Windolf, R. (1994).

Courier Forschungsinstitut Senckenberg 173:103-135. The genus was originally thought to be a eusuchian crocodylomorph, but it is now known to have been a scombrid teleostean fish.Rossmann, T. and Klappert, G. (2000).
