The Lawrence of Arabia star died on 14 December, aged 81, and he was mourned at a funeral in London last weekend.
His body was cremated and now his daughter, Kate, reveals they will be taking his remains back to Connemara to a final resting place, according to Herald.ie.
She says: "We're bringing him home. It's what he would have wanted."
The ashes will be scattered near O'Toole's hilltop retreat, which he purchased in the 1970s and boasts views of the Eyrephort peninsula.
O'Toole was born in Connemara, but his birth was registered in Leeds, England, where his parents moved to when he was a baby.
