雷利诺龙属（属名：Leaellynasaura）是种小型鸟脚下目恐龙，身长60到90公分，体重约10公斤，生存于早白垩纪阿尔比阶，化石发现于澳洲恐龙湾。

目前已发现数个雷利诺龙的化石，包含两个完整的骨骸，两个破碎的头颅骨碎片。在1989年，这些化石首次被研究、叙述。模式种是L. amicagraphica，属名是以古生物学家托马斯·里奇（Thomas Rich）与帕特·里奇（Patricia Vickers-Rich）的女儿雷利诺·里奇（Leaellyn Rich）为名。种名则意为「朋友写作」，以感谢维多利亚博物馆、国家地理学会在澳洲古生物研究上的协助。

Leaellynasaura (meaning "Leaellyn's lizard") is a genus of small herbivorous ornithischian dinosaurs from the Albian stage of the Early Cretaceous (dated to between 118 and 110 million years ago), first discovered in Dinosaur Cove, Australia. The only known species is Leaellynasaura amicagraphica. It was described in ****, and named after Leaellyn Rich, the daughter of the Australian palaeontologist couple Tom Rich and Patricia Vickers-Rich who discovered it. The specific name L. amicagraphica translates to "friend writing" and honours both the Friends of the Museum of Victoria and the National Geographic Society for their support of Australian paleontology.
