The National Union Party, commonly known as the Union Party, and sometimes as the Republican–Union coalition, was a coalition of Republicans, War Democrats, and Unconditional Unionists that supported the Lincoln administration during the American Civil War. It held the 1864 National Union Convention that nominated Abraham Lincoln for president and Andrew Johnson for vice president in the 1864 United States presidential election. Following Lincoln's assassination, Johnson tried and failed to sustain the Union Party as a vehicle for his presidential ambitions. The coalition did not contest the 1868 elections, but the Republican Party continued to use the "Union" label in subsequent elections.
