This is a list of notable individuals who were buried at the Congressional Cemetery in Washington, D.C., as well as those who are memorialized by cenotaphs. In particular, many U.S. senators and U.S. representatives are memorialized by cenotaphs at the cemetery.

Specialized terminology is used on this list. The term cenotaph includes not only monuments that are "empty tombs" or where the body is buried elsewhere, but also the graves of Congressmen who died in office which are marked by the particular style of cenotaph designed by Benjamin Latrobe for the Cemetery. "Congressman" refers to any U.S. senator or representative. A range/site listing, e.g. R31/S44, after a name gives the location of the grave or cenotaph according to the cemetery's location system.
