Cynthia Uwak grabbed the equaliser for Nigeria against Sweden
Sweden skipper Victoria Svensson put them in front just after the break, slotting past keeper Precious Dede.
But Uwak pounced on a failed clearance to slot home from 20 yards with eight minutes left.
Sweden dominated and Hanna Ljungberg hit the crossbar in the second minute, while Svensson also saw a shot hit the woodwork and bounce down on the line.
Nigeria threatened to pinch the win with a late flurry, but the draw leaves Group B wide open with all four teams on one point.
The result is an improvement for Nigeria who lost 3-0 to Sweden in the group stages of the World Cup in 2003, the Swedes eventually finished as runners-up in Russia.
The draw in Group B leaves all four teams with one point after the USA and North Korea drew 2-2 in the other Group B game on Tuesday.
The next games in Group B are on Friday with Nigeria playing North Korea while Sweden face the USA.
