What do you call someone who loves America?

Could you please elaborate on the concept of someone who holds a deep affection for America? I'm curious, what specific term or phrase do we commonly use to describe individuals who possess a profound love for this nation? Is there a single, universally recognized word that encapsulates this sentiment, or does the language offer a range of expressions to convey such patriotic fervor? I'm interested in understanding how we label those whose hearts beat with American pride.
