Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion, and a front portion. A hosel portion may have a hosel base portion attached to the top portion. A hosel upper portion may extend from the hosel base portion. A hosel transition portion may be between the hosel base portion and the hosel upper portion. The hosel transition portion may provide a gradual transition between an outer surface of the hosel base portion and an outer surface of the hosel upper portion. A shaft may be mounted on the hosel portion and may have an end portion configured to engage the hosel transition portion. Other examples and examples may be described and claimed.
