The postage stamps of German colonies were issued during the late 19th and early 20th centuries when Germany established colonies and protectorates across Africa, the Pacific, and China. Notable German colonies that issued stamps include:
- German East Africa (Tanzania, Burundi, Rwanda)
- German South-West Africa (Namibia)
- Kamerun (Cameroon)
- Togo
- German New Guinea
- German Samoa
- Kiautschou (a leased territory in China)
These stamps often featured the German Kaiser, the imperial eagle, or local motifs, and were used both for administrative purposes and to signify German sovereignty in these territories.
