The 1904 Democratic National Convention was an American presidential nominating convention that ran from July 6 through 10 in the Coliseum of the St. Louis Exposition and Music Hall in St. Louis, Missouri. Breaking with eight years of control by the Democratic Party's reform wing, the convention nominated conservative Judge Alton B. Parker of New York for president and Henry G. Davis of West Virginia for vice president.
The Democratic ticket lost in the November 1904 presidential election to the Republican Party and its ticket of Theodore Roosevelt and Charles W. Fairbanks.
