奈厄布拉勒龙属(属名:Niobrarasaurus)属于结节龙科,是群没有尾槌的甲龙类恐龙,生存于白垩纪晚期,约8700万到8200万年前。化石发现于堪萨斯州西部奈厄布拉勒组的烟山河白垩层,这个地区在晚白垩纪时期位于西部内部海道中部边缘。尼奥布拉拉龙与多刺甲龙、结节龙有接近亲缘关系。
模式种是科氏奈厄布拉勒龙(N. coleii),化石是在1930年代由地理学家Virgil Cole所发现。这些化石最初在1936年由Mehl所叙述,并命名为Hierosaurus coleii。在1995年,肯尼思·卡彭特(Kenneth Carpenter)等人将这些化石重新述叙为新属。模式标本在2002年交给堪萨斯州的斯腾伯格自然历史博物馆。
