The present invention relates to a golf ball for putting practice, in which a first concave part and a second concave part which are spaced from each other at a predetermined distance from the center of the golf ball and are formed so as to be parallel to each other along the circumferential direction of the surface of the golf ball with a predetermined depth and width, and a first ring part and a second ring part, which are inserted into the first concave part and the second concave part enable the golf ball to rotate only in the certain direction at the time of putting and enable a user to confirm the trajectory of putted golf ball to promote the efficiency of the putting practice. The present invention relates to the golf ball for putting practice, which accurately maintains the center of gravity of the surface and a core of the golf ball to improve the reliability of the golf ball, improves the stability of the golf ball for putting practice, and can reduce manufacturing cost of the golf ball for putting practice. 본 발명은 골프공의 중심에서 일정 간격 이격되고, 소정의 깊이와 폭으로 골프공의 표면의 둘레방향을 따라 서로 마주하면서 평행하도록 함입 형성되는 제1 오목부와 제2 오목부 및 제1 오목부와 제2 오목부에 삽입 체결되는 제1 링부와 제2 링부에 의해 퍼팅시에 골프공이 일정한 방향으로만 굴러가게 하고 퍼팅되는 골프공의 궤적을 확인하여 퍼팅 연습의 효율성을 도모하고, 골프공의 사출성형시에 표면과 코어의 무게중심을 정확하게 유지하여 골프공의 신뢰도를 향상시키고, 퍼팅 연습용 골프공의 안정성을 향상시키며, 퍼팅 연습용 골프공의 제조단가를 절감할 수 있는 퍼팅 연습용 골프공에 관한 것이다.
