A pump jack base (10) for a pole (12) of a pump jack scaffold (14) comprising a base plate (16). A facility (18) is for securing the base plate (16) to a generally flat support surface (20). A structure (22) is for holding a lower end of the pole (12) of the pump jack scaffold (14). An assembly (24) is for attaching the holding structure (22) to the base plate (16) in an adjustable manner. The pole (12) can be positioned within one hundred and eighty degree angle with respect to the base plate (16) to compensate for the pitch and slope of the generally flat support surface (20).
