曼特尔龙属（学名：Mantellisaurus）是种最近被重新命名的一属恐龙，原本被命名为阿瑟菲尔德禽龙（I. atherfieldensis）。
曼特尔龙的化石最初是在1914年由雷金纳德·胡利（Reginald Hooley）发现于英格兰南部，而到1917年有新闻报导。胡利最初将牠们命名为阿瑟菲尔德禽龙，是以化石发现地威特岛西南岸的阿瑟菲尔德村为名。在2007年，格里高利·保罗（Gregory S. Paul）建立曼特尔龙属，是以发现禽龙的古生物学家吉迪恩·曼特尔（Gideon Mantell）为名[1]。
根据保罗的说法，曼特尔龙的体型较禽龙小，与豪勇龙关系更接近。曼特尔龙生存于白垩纪早期的英格兰，化石包含许多完整与几乎完整的化石[1]。
与阿瑟菲尔德禽龙相比，曼特尔龙的体型较小，体重估计值约0.75公吨。曼特尔龙的前肢比例较短，而前肢长度约是后肢的一半；与贝尼萨尔禽龙相比，曼特尔龙的后肢长度约是贝尼萨尔禽龙的约70%长。由于曼特尔龙的前肢较短，身体也较短，保罗推测曼特尔龙主要采取二足方式行走，只有在静止时、缓慢行动时才会采取四足方式移动[2]。
Heterosaurus、楔椎龙、威特岛龙可能是曼特尔龙的异名。在2004年的书籍《The Dinosauria》第二版中，牠们过去曾是阿瑟菲尔德禽龙的异名[3]。但保罗的2007年研究并没有纳入这些说法。其他的可能异名包含：道罗齿龙、前扁臀龙[4]。
