The Swedish invasion of Brandenburg (1674–75) (German: Schwedeneinfall 1674/75) involved the occupation of the undefended Margraviate of Brandenburg by a Swedish army launched from Swedish Pomerania during the period 26 December 1674 to the end of June 1675. The Swedish invasion sparked the Swedish-Brandenburg War that, following further declarations of war by European powers allied with Brandenburg, expanded into a North European conflict that did not end until 1679.
