Flags whose reverse differs from the obverse
This article contains a list of flags for which the reverse (back) is different from the obverse (front). It includes current as well as historic flags of both nations and national subdivisions such as provinces, states, territories, and cities (including a few that are not recognized by the United Nations or whose sovereignty is in dispute). When the flag is that of a nation, the Subdivision column is blank. For present-day flags the Dates column is typically blank.
The list below includes flags for which the back is the mirrored reverse (exact copy) of the front. It does not include flags whose back is the mirror image (horizontally flipped) of the front, as is the case with most asymmetric flags (for example, a blue rectangle with 50 stars appears at the top left corner of the US flag. However, when viewed from behind it is seen at the top right corner). Mirrored reverse flags are much less common and contain an element for which a simple mirror image would be problematic, such as text (e.g. Saudi Arabia's flag includes the shahada, an Islamic creed) or a geographic feature (e.g. the 1970s Bangladeshi flag included a yellow map of the country). Flags with truly different images on each side are even rarer. The only UN-recognized nation whose present-day flag contains a unique image on each side is Paraguay.
