Is Congress Capitalized?

Capitalize “U.S. Congress” and “Congress” when referring to the U.S. Senate and House of Representatives. Although “Congress” sometimes is used as a substitute for the House, it properly is reserved for reference to both the Senate and House.

Capitalize “Congress” also if referring to a foreign body that uses the term, or its equivalent in a foreign language, as part of its formal name. For example,

  • the Argentine Congress
  • the Congress

Lowercase when used as a synonym for “convention” or in second reference to an organization that uses the word as part of its formal name. For example,

  • the Congress of Racial Equality
  • the congress.
