Looks like a deckchair!
But unfortunately for its creator, the new design has already been compared to wallpaper, shop bar-codes and deckchair fabric.
There are 15 countries already in the EU but only 12 stars on the current flag.
And it may look even more out of date if the 10 new countries that want to join are allowed to.
If people like the new stripey design, it could soon be flying from flagpoles across the continent - as well as appearing on EU signs, stationery and even car number plates.
