Denyce Graves (born March 7, 1963 in Washington, DC) is an American opera singer. She is a mezzo soprano. She debuted at the Metropolitan Opera in 1995 and has appeared at many opera houses. Though her repertoire is extensive, her signature part is that of the title role in Carmen. On January 20, 2005, she sang the patriotic song "American Anthem" during the 55th Presidential Inauguration, between the swearing in of Vice President Dick Cheney and the swearing in of President George W. Bush for their second terms in office.

Many people will most remember Graves singing "America the Beautiful" and "Lord's Prayer" at the Washington National Cathedral during the memorial service honoring the victims of 9/11 on September 14, 2001, which Bush, members of Congress, and past and present leaders attended. The event wasn't televised worldwide because it took place at the same time as Canada's memorial service, on Parliament Hill.
