Wade Robson, 36, told the BBC's Victoria Derbyshire programme the singer had sexually abused him from the age of seven and tried to rape him when he was 14.
James Safechuck, 40, told the programme Jackson had sexually abused him "from the age of 10 until around 14".
Jackson's family say there's "not one piece of evidence" to prove the claims.
The two men have also spoken out in the documentary Leaving Neverland.
