The grey gurnard (Eutrigla gurnardus) is a species of ray-finned fish from the family Triglidae, the gurnards and sea robins.

It is native to the eastern Atlantic Ocean, the Mediterranean Sea, and the Black Sea. It is caught as a food fish and is known for producing sounds. It is the only member of the monotypic genus Eutrigla.

The anal fin has 17–20 rays, the pectoral fins are short, just extending as far as the anal fin origin. The scales along the lateral line are slightly larger than the scales covering the body and have a spiny keel and a toothed rear edge. The breast is naked of scales while the belly is partially covered in scales.

The colour of this fish is variable but it is usually greyish-brown, rarely dull red, and tinged with red on its back and flanks. The underside is cream-coloured and the back and flanks are usually covered with small white spots.

The first dorsal fin has a large, circular black mark.
