Carli Lloyd was the United States' Olympic hero again as they avenged their World Cup final defeat by Japan and took gold in the women's football tournament with a 2-1 victory at Wembley.
Lloyd's brilliant two goals in the final were enough for the USA to complete a hat-trick of Olympic titles, as the midfielder added to her winner in the 2008 final.
They also made amends for her penalty shoot-out miss in last year's World Cup final.
Yuki Ogimi pulled a goal back for Japan, who had plenty of chances to equalise and were denied by the woodwork as they failed in a bid to add the Olympic title to their world crown.
Meanwhile, Diana Matheson scored a last-gasp goal to earn Canada the bronze medal with a 1-0 win over France at the City of Coventry Stadium.
Matheson made no mistake from close range after Sophie Schmidt's shot had deflected into her path although Kaylyn Kyle appeared to be in an offside position.
It was hard luck on France who had dominated the second half but they were to rue a series of missed chances and fine saves from Canadian keeper Erin McLeod.
