GJ 3522 (G 41–14) är en närliggande trippelstjärna i stjärnbilden Kräftan, bestående av en kortperiodisk dubbelsidig spektroskopisk dubbelstjärna och en yttre följeslagare som upptäcktes med adaptiv optik på CFHT. Systemet ligger ppå ett avstånd av 22 ljusår (6,8 parsec) från solen.

Komponenterna i den inre dubbelstjärnan kretsar kring varandra med en omloppsperiod av 7,6 dygn. Den yttre följeslagaren kretsar kring den inre dubbelstjärnan med en omloppsperiod av 5,7 år. Systemet har spektraltypen M3.5. Stjärnan visar flares i optiskt ljus och röntgenvåglängd. Den visar även aktivitet i H-alfa och ultraviolett ljus.
