Abstract: A golf ball warming device is provided for use during a round of golf. The warming device includes a main housing having a central bore which houses up to 3 golf balls. The central bore is disposed adjacent an arcuate-shaped bore which houses a disposable heating element. The heating element is chemically activated when removed from its package and radiates heat toward the golf balls disposed within its arcuate shaped bore. The golf balls and heating element are initially placed into their respective bores through a top opening within the main housing, and removed from a bottom opening when needed during play. The walls of the housing are thick in design to thermally insulate the balls within the warming device. The warming device does not use batteries, nor any other electrical current, and can operate for 5 hours at 127.degree. F. on a single heating element.
