The Democratic National Committee (DNC) is the principal committee of the United States Democratic Party. The committee coordinates strategy to support Democratic Party candidates throughout the country for local, state, and national office, as well as works to establish a "party brand". It organizes the Democratic National Convention held every four years to nominate candidates for President and Vice President of the United States and to formulate the party platform. While it provides support for party candidates, it does not have direct authority over elected officials. When a Democrat is president, the White House controls the Committee. According to Boris Heersink, "political scientists have traditionally described the parties’ national committees as inconsequential but impartial service providers."

The 1848 Democratic National Convention was a presidential nominating convention that met from Monday May 22 to Friday May 26 in Baltimore, Maryland. It was held to nominate the Democratic Party's candidates for President and Vice president in the 1848 election. The convention selected Senator Lewis Cass of Michigan for President and former Representative William O. Butler of Kentucky for Vice President.
