Dalpiazia is an extinct genus of sclerorhynchid sawfish whose fossils are found in rocks dating from the Maastrichtian stage in mines in Jordan, Libya, Morocco and Syria.^[1] The type species D. stromeri was named by Checchia-Rispoli (1933) in honor of Ernst Stromer,^[2] and the holotype, a rostral tooth, was found in Tripolitania, Libya.

The validity of Dalpiazia has been questioned on the basis of its similarities to Ischyrhiza, a subgenus of Onchosaurus.^[3]
