The Greater Milwaukee Open was a regular golf tournament in Wisconsin on the PGA Tour. For 42 years, it was played annually in July in the Milwaukee area, the final sixteen editions in the north suburb of Brown Deer at the Brown Deer Park Golf Course. U.S. Bancorp was the main sponsor of the tournament in its final years and the last purse in 2009 was $4 million, with a winner's share of $720,000. The event was run by Milwaukee Golf Charities, Inc., with proceeds going to a variety of Wisconsin charities.
The tournament debuted in 1968 as the Greater Milwaukee Open (or GMO),  competing against the British Open by offering a $200,000 purse (second highest on the Tour) with a $40,000 first prize. Lee Trevino, the recent U.S. Open winner, chose to play in the more lucrative GMO instead of the 1968 British Open. 
Art Wall Jr., the 1959 Masters champion, won in 1975 at age 51 for his first tour win in nine years,   his fourteenth and final win on the tour. Wall was one stroke ahead of 27-year-old runner-up Gary McCord, later a noted golf commentator, but winless in his career on the PGA Tour.
The tournament was played at four courses in the Milwaukee area:
|North Shore Country Club||Mequon||3||1968–1970|
|Tripoli Country Club||Milwaukee||2||1971–1972|
|Tuckaway Country Club||Franklin||21||1973–1993|
|Brown Deer Park Golf Course||Brown Deer||16||1994–2009|
It was nationally televised beginning in 1989, and Tiger Woods made his professional debut in 1996 at Brown Deer with a 67 on August 29,  four days after winning his third consecutive U.S. Amateur title in Oregon.  At age 20, he made the cut and tied for 60th place, earning a modest $2,544.  
The event ended when U.S. Bank announced that it would not renew its sponsorship after the 2009 event. Secondary sponsor Aurora Health Care also announced that it would substantially cut back on its financial involvement. Before U.S. Bank's sponsorship, the tournament survived thanks to the help of late philanthropist Jane Pettit. Its slot on the PGA Tour schedule against the British Open, along with low attendance and TV ratings, were reasons cited by U.S. Bank for pulling out of the event.  The Greater Milwaukee Charities organization has closed its offices and has shut down.
