Lirainosaurus (meaning "slender lizard"; from the Basque lirain, meaning "slender", and the Greek sauros, meaning "lizard") is a genus of titanosaur sauropod which lived in what is now Spain. The type species, Lirainosaurus astibiae, was described by Sanz, Powell, Le Loeuff, Martinez, and Pereda-Suberbiola in 1999. It was a relatively small sauropod, measuring 4 metres (13 ft) long, possibly up to 6 metres (20 ft) long for the largest individuals, and weighed about 2–4 metric tons (2.2–4.4 short tons).
