This comes after five weeks of voting to consider redesigns for the flag.
"Some may call it an SOB - a seal on a bedsheet - and the vexillogical community may hate it, but people overwhelmingly prefer our current state flag," Giannoulias said. "Thank you to everyone who made their voice heard on the future of this important symbol of state pride."
There were nearly 386,000 votes received in the contest, with more than 165,000 or 43 percent, cast for the current flag, which was more than the next five top designs combined.
