The Cronulla rugby league ground, offered by penultima thule, is a pretty decent candidate. I’ve been to games there under 4 of those 6 names.
But i’ve managed to go one better, here in the US. The stadium where the Miami Dolphins NFL team and Florida Marlins baseball team play is currently in its seventh different name.
Joe Robbie Stadium (1987-1996)
Pro Player Park (1996)
Pro Player Stadium (1996-2005)
Dolphins Stadium (2005-2006)
Dolphin Stadium (2006-2009; 2010)
Land Shark Stadium (2009-2010)
Sun Life Stadium (2010- )
Some multiple named stadiums (though none that hold the record)
Jack Murphy Stadium/Qualcomm Stadium/San Diego Stadium
Dodger Stadium/Chavez Ravine Stadium (of note because it used both names at the same time).
Sportsman’s Park/Busch Stadium (St. Louis)
Shibe Park/Connie Mack Stadium (Philadelphia)
Two stadiums in different cities that had the same name: Wrigley Field (Los Angeles and Chicago)
The SF Giants’ home stadium has had three names in its short life:
Pacific Bell Park
The Giants’ former home has had four names:
3Com Park at Candlestick Point
San Francisco Stadium at Candlestick Point
The Houston Astros’ home ground has had four:
The Ballpark at Union Station
Minute Maid Park
The Baltimore Ravens’ home ground has had four:
Ravens Stadium at Camden Yards
M&T Bank Stadium
I really think we’re unlikely to find a stadium that will beat the one mentioned in the OP. One reason is that, at least in the US, and especially in baseball, most stadiums are either quite new (the post-Camden Yards rise of new-style stadiums) and haven’t had much time for multiple name changes, or they are old and venerable, with names that haven’t changed in decades (Wrigley, Fenway, Dodger Stadium, etc.). Even most NFL stadiums are quite new (<20 years), and the older one tend to have traditional names that have remained unchanged for a long time.
As far as i can tell, none of the 20 English Premier League stadiums has had more than a couple of names, and a few of them, like Turf Moor, have had the same name going well back into the nineteenth century.
Extremely pedantic nitpick: No it didn’t. When the Dodgers were at home, it was called Dodger Stadium. When the Angels were at home, it was called just Chavez Ravine. Nobody ever appended the “Stadium.” And they never played home games on the same day, so it was never known as both at the same time.
There was a 2-month period in 2005, between the end of the Fleet contract and the beginning of the TD one, where they put the official name up for auction on eBay every day, I think for the Jimmy Fund. They retained veto power, to keep some New Yorker’s every-single-day bid for “Derek Jeter Center” from winning. That period might have made it the winner here, if they’d ever publicly released a full name of winners.
But we do know that for two days it was the Yankees Suck Center.
You know, I was about to nitpick this and say that Sportsman’s Park and Busch Stadium were different ballparks at different locations, but according to Wikipedia Sportsman’s Park had been called Busch Stadium since the early 50’s. Having grown up in St Louis, you’d think I would know that, but I have never heard of Sportsman’s Park being called anything but Sportsman’s Park. Ignorance has been fought!
I seem to recall that GM place in Vancouver was renamed “Canada Hockey Place” for the duration of the Olympics because of an IOC rule prohibiting corporate names for olympic venues. For the same reason, the arena then know as Delta Center, but now known as Energy Soutions Arena, was renamed “Olympic Ice Center” during the 2002 games.
