A public appeal was made over the weekend for anyone who had seen Natasha or had information about her whereabouts to report it to police.
A police spokesperson said at the time she was last seen on Devon St, Sydenham.
But on Tuesday morning police said Natasha had been found.
"The 12-year-old reported missing on 11 July from the Sydenham area has been located safe and well.
"Thank you everyone who shared our appeal."
