Other "LPGA's" exist in other countries, each with a geographical designation in its name, but the U.S. organization is the first, largest, and best known. The LPGA is also an organization for female club and teaching professionals. This is different from the PGA Tour, which runs the main professional tours in the U.S. and, since 1968, has been independent of the club and teaching professionals' organization, the PGA of America.

The LPGA also administers an annual qualifying school similar to that conducted by the PGA Tour. Depending on a golfer's finish in the final qualifying tournament, she may receive full or partial playing privileges on the LPGA Tour. In addition to the main LPGA Tour, the LPGA also owns and operates the Symetra Tour, formerly the Futures Tour, the official developmental tour of the LPGA. Top finishers at the end of each season on that tour receive playing privileges on the main LPGA Tour for the following year.
