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.
