梅尔菲森特（Maleficent、又译玛列菲森、那达生、黑巫婆、魔莉妃和梅菲瑟），是1959年迪斯尼动画电影《睡美人》中的虚构角色。

自称为“万恶女神”，是深居禁忌之山魔窟中的坏仙子。因为公主诞生的庆典没受到邀请而对公主施下诅咒。故事末尾与菲利普王子对决时变身为巨大的黑色喷火龙，后被王子用神剑刺死。

她被认为是迪士尼反派中最强大和最凶恶的角色，很多时候被视为这些反派角色中的头目。

Maleficent (/məˈlɛfɪsənt/ or /məˈlɪfɪsənt/) is the antagonist of Walt Disney's 1959 film Sleeping Beauty. She is characterized as the "Mistress of All Evil" who, after not being invited to a christening, curses the infant Princess Aurora to "prick her finger on the spindle of a spinning wheel and die" before the sun sets on Aurora's sixteenth birthday. She was voiced by Eleanor Audley, who earlier voiced Lady Tremaine in Cinderella (1950). Maleficent was created by Marc Davis and is based on the evil fairy godmother from the original fairy tale of the same name by Charles Perrault and The Brothers Grimm.
