The assassination of John F. Kennedy, the thirty-fifth President of the United States, took place on Friday, November 22, 1963, in Dallas, Texas, USA at 12:30 p.m. CST (18:30 UTC). Kennedy was fatally wounded by gunshots while riding with his wife in a presidential motorcade through Dealey Plaza. He was the fourth U.S. President to be assassinated and the eighth to die while in office.

An official investigation by the Warren Commission was conducted over a 10-month period, and its report was published in September 1964. The Commission concluded that the assassination was carried out solely by Lee Harvey Oswald, an employee of the Texas School Book Depository in Dealey Plaza. This conclusion initially met with widespread support among the American public, but polling in recent years shows a majority of that public now hold beliefs contrary to the Commission's findings. [1] A later official investigation by the House Select Committee on Assassinations (HSCA) was conducted from 1976 to 1979, and it concluded that Kennedy was assassinated by Oswald "probably... as a result of a conspiracy". The assassination is still the subject of widespread speculation, and has spawned a number of Kennedy assassination theories.

肯尼迪遇刺是指美国第三十五任总统约翰·肯尼迪肯尼迪遇刺是指美国第三十五任总统约翰·菲茨杰拉德·肯尼迪于1963年11月22日星期五下午12:30，在夫人杰基·肯尼迪（Jackie Kennedy）和德克萨斯州州长约翰·康纳利（John Connally）陪同下，乘坐敞蓬轿车驶过德克萨斯州达拉斯市的迪利广场（Dealey Plaza）时，遭到枪击身亡。约翰·肯尼迪是美国历史上第四位遇刺身亡的总统，也是第八位在任期内去世的总统。负责总统遇刺案调查工作的沃伦委员会（the Warren Commission）在经过了长达10个月的调查之后，于1964年9月发表了一份官方报告，在此份报告中指出，刺杀肯尼迪的凶手是德克萨斯州教科书仓库大楼的雇员李·哈维·奥斯瓦尔德（Lee Harvey Oswald），正是他从教科书大楼六层上的窗口向乘坐敞篷车正从楼下经过的总统开枪将其刺杀的。一个后来成立的官方调查委员会——众议院遇刺案特派委员会（the House Select Committee on Assassinations ，HSCA）从1976年到1979年再次对总统遇刺案进行了详细的调查取证，并得出结论认为，奥斯瓦尔德刺杀肯尼迪绝不是个人行为。迄今为止，肯尼迪遇刺案仍然存在着很多置疑，引起了人们的广泛猜测，并且产生了许多关于肯尼迪遇刺案的理论。
