黑丘龙科（Melanorosauridae）是蜥脚形亚目的一个科，生存于晚三叠纪到早侏㑩纪。黑丘龙科最初是由古生物学家休尼（Friedrich von Huene）所创建。休尼并将近蜥龙科、板龙科、槽齿龙科、以及黑丘龙科归类于原蜥脚下目。后来，这些科有多次的修改。在2004年，彼得·加尔冬与彼得·阿普彻奇将黑丘龙、莱森龙、卡米洛特龙归类于黑丘龙科。在2007年，亚当·耶兹指出黑丘龙科是种早期蜥脚下目恐龙。里奥哈龙科的里奥哈龙、优胫龙也曾被归类于黑丘龙科，如果两者都属于黑丘龙科，里奥哈龙科将成为无效的分类单元。

The Melanorosauridae were a family of sauropodomorph dinosaurs which lived during the Late Triassic and Early Jurassic. The name Melanorosauridae was first coined by Friedrich von Huene in 1929. Huene assigned several families of dinosaurs to the infraorder "Prosauropoda": the Anchisauridae, the Plateosauridae, the Thecodontosauridae, and the Melanorosauridae. Since then, these families have undergone numerous revisions. Galton and Upchurch (2004) considered Camelotia, Lessemsaurus, and Melanorosaurus members of the family Melanorosauridae. A more recent study by Yates (2007) indicates that the melanorosaurids were instead early sauropods. The two members of the Riojasauridae, Riojasaurus and Eucnemesaurus, have also been placed in Melanorosauridae, which would render the Riojasauridae an invalid taxon.
