自然界存在α-蒎烯和β-蒎烯，它们之间属双键的位置异构。这两种蒎烯是松节油的主要成分（蒎烯英文名即出自松树），也存在于其它松柏门植物中。在针叶植物以外的种类中也发现其存在，比如一种菊科植物Heterotheca（英语：Heterotheca）^[3]以及大鼠尾草（三齿蒿（英语：Artemisia tridentata））。

生物体内，α-蒎烯和β-蒎烯都是由香叶基焦磷酸酯转化生成的。反应机理经过酯基异构化，首先得芳樟醇焦磷酸酯，接着环化重排，然后从碳正离子失去一个质子得到产物。

α-蒎烯是自然界中最广泛分布的萜烯之一，^[4]具有强烈的驱虫性。^[5]

α-蒎烯主要存在于针叶树等植物。^[6]也是毒马草属和鼠尾草属植物精油的主要成分。^[7]^[8]大麻属也含α-蒎烯。^[6] 圆柄黄连木的树脂富含蒎烯。松子中也存在。^[6]

箭叶橙的果皮精油主要成分为柠烯和β-蒎烯。^[9]

化学工业上，蒎烯的催化氧化得到各种人工香料，如马鞭烯酮等。^[10]
