徐枫原籍江苏宝应，1950年出生于台北。在就读于育达商职二年级时，便考入了联邦电影公司，当年她才16岁。她的银幕处女作是与上官灵凤、苗天等人主演的，胡金铨执导的《龙门客栈》，上官灵凤凭借该片获得了上一届的金马影后称号，而初出茅庐的徐枫也凭借这部处女作赢得瞩目，开始了其星光闪闪银幕生涯。

　　在上官灵凤一样，最初的徐枫也是以拍摄古装武侠片为主，曾在多部古装武侠片中担任女主角。她主演的这类影片较著名的有《侠女》、《黑道行》等。凭借在《侠女》中的出色表演，她曾当选第九届台湾电影金马奖最有希望女星。1976年，徐枫达到自己个人演艺生涯的第一个高峰，凭借在《刺客》一片中的出色表演，她获得了当年的第十三届金马奖最佳女主角奖。之后她又接连主演了《八百壮士》、《血连环》、《侠士、镖客、杀手》等一系列影片。

　　在1979年，她和归亚蕾等人主演了陈耀圻执导的历史题材的传奇影片《源》。据说该片的完整版本长达3小时30分，但发行时却删剪为2小时10分，因此似的本片显得有不少场面交代不清，但尽管如此徐枫饰演的主人翁吴霖芳却为她赢得了一片喝彩声，该片又为她赢得第十七届金马奖最佳女主角奖。除了几度扬威金马奖之外，徐枫1974年主演的《大摩天岭》一片还为她赢得了第二十二届亚太影展金皇冠盾牌奖。演艺事业达到顶峰的徐枫，在再次摘得金马影后之后，在银幕上继续自己的辉煌事业。
