World champion Tina Trstenjak of Slovenia made it a golden double by winning the Olympic under-63kg judo title in Rio on Tuesday.
Trstenjak defeated France's Clarisse Agbegnenou, whom she had succeeded as world champion, in the final by immobilisation.
In doing so, she succeeded countrywoman Urska Zolnir as Olympic champion.
"Amazing, so super. I have no words," said the new champion.
The bronze medals went to Israel's 2013 world champion Yarden Gerbi and Anicka van Emden of the Netherlands.
The decisive moment in the final came when Trstenjak countered a hasty attack from Agbegnenou before securing a hold down, from which the French woman could not escape.
Agbegnenou said she'd been impatient.
"I'm disappointed, I'm very disappointed with myself," she told French television.
"But then, I'm still going home with a silver medal. I'm disappointed but I have to accept it.
"I was too rushed, I tried to throw her, to find an opening but I was too hurried.
"I don't want to talk about judo right now."
