Jefferson–Jackson Day is the annual fundraising celebration (dinner) held by Democratic Party organizations in the United States. It is named for Presidents Thomas Jefferson and Andrew Jackson, which the party calls its founders. During presidential election campaigns, key dinners are important venues for candidates to attend. It is usually held in February or March around the same time as the Republican Party's equivalent Lincoln Day, Reagan Day, or Lincoln–Reagan Day dinners. The Iowa dinner is held in November so as to precede the state's caucuses for the Democratic presidential nomination.
