What is Chrono Trigger's name?

Excuse me, could you please clarify something for me? I've come across a reference to a game or perhaps a specific item within a game, called "Chrono Trigger," and I'm a bit confused. Is "Chrono Trigger" actually a name of a character, or is it referring to the title of a game? If it's the latter, then I apologize for the confusion, but if it's a character's name, could you elaborate on who that character is and what role they play in the game? I'm genuinely curious and would appreciate your insight.
