Proxima Centauri (Latinets proxima = "närmast") är den stjärna som ligger närmast solen. Den tillhör stjärnbilden Kentauren och trippelstjärnsystemet Alfa Centauri, där den kretsar runt dubbelstjärnan Alfa Centauri med en omloppstid på omkring 550 000 år. Den skenbara magnituden på +11,05 gör att stjärnan endast syns i teleskop.
