The 2008 Mississippi Democratic presidential primary took place on March 11, 2008, with 33 delegates at stake. The winner in each of Mississippi's four congressional districts was awarded all of that district's delegates, totaling 22. Another 11 delegates were awarded to the statewide winner, Barack Obama. The 33 delegates represented Mississippi at the Democratic National Convention in Denver, Colorado. Seven other unpledged delegates, known as superdelegates, also attended the convention and cast their votes as well.
