Prohalecites is an extinct genus of ray-finned fish from the Ladinian and possibly Carnian (Triassic) of Italy.[2] It is the oldest known teleosteomorph, a group that includes extant teleosts and their close fossil relatives.[3]

The type and only known species, Prohalecites porroi, was first described as "Pholidophorus porroi" by , but it was later accommodated in its own genus by . The species "Pholidophorus" microlepidotus has occasionally been included in this genus as well, but it differed greatly from P. porroi in several respects, indicating that it was not closely related.[2]

Species of Prohalecites are small, often measuring not more than 4 centimetres (1.6 in) in body length.[4]
