Philly, derived from Philadelphia, is an uncommon given name of American origin. It is often used as a nickname for individuals named Philip but can also stand alone as a unique moniker. The name Philly gained some popularity in the early to mid-20th century, likely influenced by the city it is derived from. However, it has not been widely used and thus retains an air of uniqueness.
