密耳拉（古希腊语：Μύρρα，字面意思为“没药”）希腊神话中的塞浦路斯公主，著名的美少年阿多尼斯的母亲。

根据神话，密耳拉是塞浦路斯国王喀倪剌斯的女儿，母亲为肯刻瑞伊斯（或墨塔耳墨）。密耳拉的母亲竟敢夸口说自己女儿的美貌与女神阿佛罗狄忒不相上下，令后者勃然大怒。阿佛罗狄忒对密耳拉施下诅咒，使她爱上了自己的父亲喀倪剌斯。密耳拉知道无法与父亲结合，于是产生了轻生的念头，企图上吊自杀，但被乳母希波吕塔所救。希波吕塔心疼密耳拉，于是不惜设计帮助她与父亲乱伦。在希波吕塔帮助下，密耳拉与喀倪剌斯同床12夜之久。但在第12天夜里，喀倪剌斯终于发现与他交欢的女人是自己的女儿，暴怒之下拿起刀准备将密耳拉杀死。密耳拉向神呼救，众神于是把她变成了一棵没药树。这时密耳拉已经怀上了喀倪剌斯的孩子。10个月后，没药树的树皮渐渐隆起，在助产女神厄勒梯亚帮助下，树皮破裂，生出一个男婴，就是阿多尼斯。

Myrrha (Greek: Μύρρα), also known as Smyrna (Greek: Σμύρνα), is the mother of Adonis in Greek mythology. She was transformed into a myrrh tree after having had intercourse with her father and gave birth to Adonis as a tree. Although the tale of Adonis has Semitic roots, it is uncertain from where the myth of Myrrha emerged, though it was likely from Cyprus.
