蒎烯（Pinene）是一類具有相同骨架結構的天然有機化合物，屬於雙環單萜，分子式C10H16。[1]

自然界存在α-蒎烯和β-蒎烯，它們之間屬雙鍵的位置異構。這兩種蒎烯是松節油的主要成分（蒎烯英文名即出自松樹），也存在於其它松柏門植物中。在針葉植物以外的種類中也發現其存在，比如一種菊科植物Heterotheca[3]以及大鼠尾草（三齒蒿）。

生物體內，α-蒎烯和β-蒎烯都是由香葉基焦磷酸酯轉化生成的。反應機理經過酯基異構化，首先得芳樟醇焦磷酸酯，接著環化重排，然後從碳正離子失去一個質子得到產物。

α-蒎烯是自然界中最廣泛分布的萜烯之一，[4]具有強烈的驅蟲性。[5]

α-蒎烯主要存在於針葉樹等植物。[6]也是毒馬草屬和鼠尾草屬植物精油的主要成分。[7][8]大麻屬也含α-蒎烯。[6]圓柄黃連木的樹脂富含蒎烯。松子中也存在。[6]

箭葉橙的果皮精油主要成分為檸烯和β-蒎烯。[9]

化學工業上，蒎烯的催化氧化得到各種人工香料，如馬鞭烯酮等。[10]
