哈利·本傑明（英語：Harry Benjamin，1885年1月12日—1986年8月24日）是一位德裔美国內分泌學家和性學家，因其对跨性别者的临床工作而闻名。


其他工作和兴趣 除了內分泌學和性學之外，他還研究生命延續，現在可以被稱為老年學家。班傑明活到了101歲。
班傑明將他在1966年的主要著作獻給了格蕾琴（Gretchen）。他們結婚長達60年，於1925年12月23日結婚。格蕾琴向查爾斯·L·伊倫菲爾德（Charles L. Ihlenfeld）透露，「他們結婚約六個月後，哈利從德國把母親接來與他們同住」，而且「從那時起，他們的臥室門就一直開著」。
1979 年，「哈利本傑明國際性別焦慮協會」成立，並經班傑明授權以他的名字命名。該組織由治療師和心理學家組成，他們制定了一套「性別不安診療標準」（Standards of Care, SOC），主要基於班傑明的案例與研究。該組織後來更名為「世界跨性別健康專業協會」。
