Depends where you are. Most major countries agree that only sparkling wine made under strict conditions and specifications in Champagne, France can legally be named champagne. The USA is the stand out exception. They adopted the international standard in 2006 (over 100 years after mostly everyone else). The name can still be used in the US for non-Champagne champagnes if they were used on a specific product prior to 2006 and also give the true origin.
