The Greater Jacksonville Open was a PGA Tour event that was played from 1945 until 1976.

Shortly after World War II, the Jacksonville Open began play as a PGA Tour event in Jacksonville, Florida at the Hyde Park Golf Club until it was discontinued in the mid-1950s.

The Greater Jacksonville Open was discontinued after the 1976 tournament when the PGA Tour decided to relocate The Players Championship to Ponte Vedra Beach, Florida.

The PGA Tour had been looking for some time for a permanent home for the marquee event which has professional golf's highest prize fund and is sometimes referred to as the "fifth major".

The Greater Jacksonville Open laid the groundwork and provided much of the infrastructure for the modern Players Championship, which was first played in Ponte Vedra Beach in 1977.
