Josateki Naulu is the fourth judoka to be Fiji's flag bearer at the London Olympics.
Chef de mission Chris Yee said the nominations for Team Fiji's flag bearer was called by the participating National Federations.
Viliame Takayawa Sr, Nacanieli Takayawa and Sisilia Nasiga were the other judoka's to fly Fiji's flag at the past Olympics respectively.
"From the nominations received, Josateki (Naulu) was the highest internationally ranked Fiji athlete," Yee said in a press statement.
Naulu is currently ranked 34/264 in the world in his weight category of 81kg with 284 points.
He also won Gold medal at the 2011 Pacific Games in Noumea and repeated the feat at the Oceania Judo Championships in Australia earlier this year.
"Josateki was the top male athlete selected by the Oceania Judo Union for the continental quota place where he was ranked third behind two females from Australia and New Zealand," he said.
Josateki is based in Japan where he trains with his coach Takashi Iwasaki.
His section manager Nacanieli Takayawa said for Naulu it was a humble experience to carry the flag.
"It is a prestige to lead your country with the flag from the front at the Olympics," he said.
Meanwhile, Fiji will be represented by nine athletes and 14 officials.
Yee was realistic of their chances saying they can only hope for the best.
"Fiji has the potential to mould the athletes to Rio 2016 Olympics but just not yet," he said.
