The objective of the present invention is to bring hit feeling of two-piece balls closer to that of thread-wound golf balls. The two-piece golf ball of the present invention comprises a core formed from a rubber composition comprising a base rubber, a co-crosslinking agent and an organic peroxide, and a cover covering the core, wherein said core has the following hardness distribution when measured by a JIS-C hardness meter;(1) hardness at a center: 58-73(2) hardness at 5-10 mm from the center: 68-78(3) hardness at 15 mm from the center: 76-88(4) surface hardness: 78-88(in the hardness distribution, hardness (2) is substantially constant being within the above range, of which tolerance is within .+-.3 and the other values satisfy the relation of (1)
