肯尼迪家族（英语：Kennedy family）是一个对美国政冶有重要影响的爱尔兰裔美国人家族，老约瑟夫·P·肯尼迪与罗斯·菲茨杰拉德·肯尼迪的后代。肯尼迪家族主要参与美国民主党的政治活动。他们很多都拥有哈佛大学的学历，并经常捐助哈佛大学约翰·F·肯尼迪政府学院。家族成员的财富、魅力以及对公共事务的持续参与，使肯尼迪家族成为了美国过去半个多世纪里的文化符号。

1960年美国总统选举后，总统约翰·肯尼迪以及他的两位弟弟罗伯特·肯尼迪与爱德华·肯尼迪都在联邦政府中担任要职，并因为他们的年轻、魅力、教育背景等获得了公众的广泛关注。从1947年约翰·肯尼迪进入国会，到2011年帕特里克·肯尼迪离开国会，肯尼迪家族在长达64年的时间里都在华盛顿担任公职。

The Kennedy family is an American family of Irish descent that is prominent in American politics, government, public service, and business during the mid-to-late 20th century. The first Kennedys to reside in America were Patrick Kennedy and Bridget Murphy, who sailed from Ireland to America in 1849. Their son P. J. went into politics and business. P. J. and his wife Mary Hickey were the parents of businessman and politician Joseph P. Kennedy, Sr. The nine children of Joseph Sr. and Rose Fitzgerald were Joseph Jr., John, Rosemary, Kathleen, Eunice, Patricia, Robert, Jean, and Ted. John served as president, while Robert and Ted both became prominent senators. The Kennedys' political involvement has revolved around the Democratic Party. Harvard University educations have been common among them, and they have contributed heavily to that university's John F. Kennedy School of Government. The wealth and glamour of the family members, as well as their extensive and continuing involvement in public service, have elevated them to iconic status over the past half-century, with the Kennedys sometimes referred to as "America's Royal Family".
