The present invention relates to a portable golf ball cleaner to wipe off dirt attached to a surface of a golf ball during playing of golf. The golf ball cleaner comprises a cleaner body including a concave portion having a curved surface, a wipe-off part formed on an inner wall surface of the concave portion, and a lid to open and close the concave portion of the cleaner body. Because the golf ball cleaner can be easily carried by a golf player, by putting it in a pocket or hanging it from the waist, and the player is capable of rotating the golf ball in the concave portion having the curved surface while securely holding the golf bail by hand, the dirt attached to the surface of the golf ball can be thoroughly wiped off by the wipe-off part.
