巨板龍屬(屬名:Macroplata)是已滅絕海生爬行動物的一屬,是種原始蛇頸龍類動物,生存於侏儸紀早期,身長可達4.5公尺。如同其他蛇頸龍類,巨板龍可能以小型魚類為食,並使用牠們銳利的針狀牙齒來捕捉獵物。巨板龍的肩部骨頭相當大,顯示牠們快速游泳時,有非常巨大的前進力量。相較於更先進的上龍類,巨板龍擁有相當長的頸部,是頭顱骨的兩倍長[1]

巨板龍目前已有兩個已承認屬:模式種小頭巨板龍M. tenuiceps),生存於早侏儸紀赫唐階、長吻巨板龍(M. longirostris),生存於稍晚的托阿爾階。然而長吻巨板龍被認為足夠特別,可以列於個別的屬。在2011年,長吻巨板龍被改歸類於Hauffiosaurus的一種。
