The name  Papiermark (help·info) (English: paper mark, officially just Mark, sign: ℳ) is applied to the German currency from the 4th August 1914 when the link between the Goldmark and gold was abandoned, due to the outbreak of World War I. In particular, the name is used for the banknotes issued during the hyperinflation in Germany of 1922 and especially 1923 (see Inflation in the Weimar Republic), which was a result of the German government's decision to pay its war debt by printing banknotes.

From 1914, the value of the Mark fell. The rate of inflation rose following the end of World War I and reached its highest point in October 1923. The currency was stabilized in November, 1923 after the announcement of the creation of the Rentenmark, although the Rentenmark did not come into circulation until 1924. When it did, it replaced the Papiermark at the rate of 1 trillion Papiermark = 1 Rentenmark. Later in 1924, the Rentenmark was replaced by the Reichsmark.

In addition to the issues of the government, emergency issues of both tokens and paper money, known as Kriegsgeld (war money) and Notgeld (emergency money), were produced by local authorities .
