The 1944 Democratic National Convention was held at the Chicago Stadium in Chicago, Illinois from July 19 to July 21, 1944. The convention resulted in the nomination of President Franklin D. Roosevelt for an unprecedented fourth term. Senator Harry S. Truman of Missouri was nominated for vice president. Including Roosevelt's nomination for the vice-presidency in 1920, it was the fifth time Roosevelt had been nominated on a national ticket. The keynote address was given by Governor Robert S. Kerr of Oklahoma, in which he "gave tribute to Roosevelt's war leadership and New Deal policies."

The 2020 Democratic National Convention was a presidential nominating convention that was held from August 17 to 20, 2020, at the Wisconsin Center in Milwaukee, Wisconsin, and virtually across the United States. At the convention, delegates of the United States Democratic Party formally chose former vice president Joe Biden and Senator Kamala Harris of California as the party's nominees for president and vice president, respectively, in the 2020 United States presidential election.
