Flags depicting the Southern Cross

The Southern Cross or Crux, a constellation visible in the Southern Hemisphere, is depicted on flags and coats of arms of various countries and sub-national entities.This star constellation is visible mostly in the southern hemisphere and it therefore symbolises the southern location of its users.The term Southern Cross can also refer to the blue saltire as used in various flags of the Confederate States of America in the American Civil War.Flag proportions may vary between the different flags, and sometimes even vary between different versions of the same flag.Presidential Standard of BrazilVice Presidential Standard of BrazilFlag of the Minister of Defense of BrazilFlag of the Federal SenateFlag of AssisFlag of Bom Sucesso do SulFlag of Cachoeiro de ItapemirimFlag of Cruzeiro do Sul, AcreFlag of DiamantinoFlag of ExtremaFlag of GoiásFlag of GoioerêFlag of IgaporãFlag of IjuíFlag of Ilha CompridaFlag of ItamarandibaFlag of ItauçuFlag of JaguaripeFlag of JoinvilleFlag of LondrinaFlag of MairiporãFlag of MaringáFlag of Monte Santo, BahiaFlag of ParanáFlag of Cruzeiro do Sul, ParanáFlag of PeruíbeFlag of PindamonhangabaFlag of QuaraíFlag of Rio Claro, Rio de JaneiroFlag of TeféQueen's Personal New Zealand Flag (1962–2022)Flag of the governor-generalFlag of NiueFlag of TokelauNew Zealand Red EnsignRoyal New Zealand Navy EnsignNew Zealand Civil Air EnsignNew Zealand Police EnsignBurgee of the Royal New Zealand Yacht SquadronEnsign of the Royal New Zealand Yacht Squadron
