In politics, a red flag is a symbol of socialism, communism, and left-wing politics; it has been associated with left-wing politics since the French Revolution (1789–99). Socialists adopted the symbol during the Revolutions of 1848 and it became a symbol of communism as a result of its use by the Paris Commune of 1871. The flags of several communist states, including China, Vietnam and the Soviet Union, are explicitly based on the original red flag. The red flag is also used as a symbol by some democratic socialists and social democrats, for example the Avami National Party of Pakistan, French Socialist Party and the Social Democratic Party of Germany. The Labour Party in Britain used it until the late 1980s. It was the inspiration for the socialist anthem, The Red Flag.

In many countries a red flag is flown to signify that an outdoor shooting range is in use. The United States Air Force refers to its largest annual exercise as red flag operation. Red flags are used for various signals in team sailing races (see Racing Rules of Sailing). A red flag warning is a signal of high wildfire danger and a red flag on the beach warns of dangerous water conditions (double red flags indicate beach closure). Red flags of various designs indicate dangerous wind and wave conditions for mariners. In auto racing, a red flag indicates a stop to the race due to dangerous conditions.

For example, email spam filters make use of such "red flags".
