Pteranodon (/tɪˈrænədɒn/; dari Yunani πτερόν (pteron, "sayap") dan ἀνόδων (anodon, "tak bergigi")) adalah genus pterosaurus yang termasuk beberapa reptil terbang terbesar yang pernah diketahui, dengan rentang sayap melebihi 7 meter (23 kaki). Mereka hidup selama periode geologi Kapur di Amerika Utara yang sekarang dikenal dengan Kansas, Alabama, Nebraska, Wyoming, dan South Dakota. Spesimen fosil Pteranodon telah ditemukan lebih banyak daripada pterosaurus lain, dengan sekitar 1,200 spesimen yang diketahui, sebagian besar terawetkan dengan baik dengan tengkorak-tengkorak yang hampir lengkap dan kerangka yang terartikulasi. Hewan ini termasuk bagian penting dari komunitas hewan dalam Laut Interior Barat.[1]

Pteranodon adalah pterosaurus, yang berarti bukan termasuk dinosaurus. Secara definisi, seluruh dinosaurus termasuk salah satu dari dua kelompok dalam klad Dinosauria, contohnya Saurischia atau Ornithischia. Dengan demikian, ini tidak termasuk pterosaurus. Namun, Pteranodon seringkali muncul dalam media dinosaurus dan sangat terkait dengan dinosaurus oleh masyarakat umum.[2] Meskipun tidak termasuk dinosaurus, pterosaurus seperti Pteranodon membentuk klad yang berkerabat dekat dengan dinosaurus karena keduanya termasuk dalam klad Avemetatarsalia.
