A whistle stop or whistle-stop tour is a style of political campaigning where the politician makes a series of brief appearances or speeches at a number of small towns over a short period of time. Originally, whistle-stop appearances were made from the open platform of an observation car or a private railroad car.

A political campaign is an organized effort which seeks to influence the decision making progress within a specific group. In democracies, political campaigns often refer to electoral campaigns, by which representatives are chosen or referendums are decided. In modern politics, the most high-profile political campaigns are focused on general elections and candidates for head of state or head of government, often a president or prime minister.
