A golf hole marker, having a self-righting structure, includes a base, a weighting material received in the base, a telescopic pole and a flag. The base includes a top shell and a bottom shell. The bottom shell is substantially spherically curved and receives the weighting material therein. The top shell has a passage to receive a bottom portion of the pole and a protuberance to press down the weighting material for preventing the weighting material from moving within the bottom shell. The weighting material lowers a center of mass of the golf hole marker lower than a center of the spherically curved bottom shell. Preferably, the base is in the shape of a golf ball.
