Gracilineustes is an extinct genus of marine crocodyliform that lived in the oceans during the Middle to Late Jurassic. Gracilineustes was a carnivore that spent much, if not all, its life out at sea. It was a small reptile, with G. leedsi measuring 2.25–3.11 m (7.4–10.2 ft) long and G. acutus measuring 3.77 m (12.4 ft) long.
