安娜（Anna）是希伯来语名字“汉娜”（希伯来语：חַנָּה 或 Channah‎）的拉丁版本，意为“优雅”、“恩惠”。“安娜”在英语国家的使用已有数百年的历史，最初的原始英文拼写是“Ann”（安）。而在世界范围内，一个更加流行的拼写版本是来自法语的拼法“Anne”。“安娜”一名的最早使用是在天主教中圣母玛利亚的母亲“圣安娜”。这位圣人的名字使得“安娜”一名在基督徒中开始被广泛使用。在西方历史中，有几位圣人或女王亦取名“安娜”。在荷兰语中，“安纳”也可作为男性的名字，如安纳·德·弗里斯。

Anna is a Latin form of the Greek name Ἅννα and the Hebrew name Hannah (Hebrew:חַנָּה Ḥannāh‎, meaning "favor" or "grace"). Anna is in wide use in countries across the world as are its variants Anne, originally a French version of the name, though in use in English speaking countries for hundreds of years, and Ann, which was originally the English spelling. Saint Anne was traditionally the name of the mother of the Virgin Mary, which accounts for its wide use and popularity among Christians. The name has also been used for numerous saints and queens.
