This page lists the IDs of NPCs in Terraria. This includes monsters, critters, friendly NPCs (otherwise just referred to as 'NPCs'), bosses, some projectiles, and creature parts if the creature is composed of more than one.
NOTE: All NPCs have IDs, however, newer NPCs and variations of certain types use negative numbers as their identifiers. They're listed here for completeness' sake.
