Torvosaurus (TOR-voh-SAWR-us) was a giant carnivorous dinosaur, similar in appearance to Tyrannosaurus although it had larger 'arms' and a bulky body.

It lived about 145 million years ago, in the late Jurassic Period of what is now North America (and perhaps Portugal). It reached 10 to 12 meters (33 to 40 feet) in length and an estimated weight of 2 to 3 tonnes (2 to 3 tons), which made it the largest carnivore of its time. This bipedal meat-eater was up to 40 feet (12 metres) long and had extremely short arms. It lived during the Kimmeridgiann age, about 156-145 million years ago in what is Colorado, USA, North America.

The type species is T. tanneri. Torvosaurus was named by paleontologists Galton and Jensen in 1979.
