Omar Maute and Isnilon Hapilon were killed during a Philippine Armed Forces operation earlier today, Defence Secretary Delfin Lorenzana said.
Mr Lorenzana said he now expects to announce the end of hostilities in Marawi within days — although previous predictions like this have come and gone.
Omar Maute and his brother Abdullah were responsible for planning the attack on Marawi in late May.
The brothers aligned themselves with Isnilon Hapilon, a former leader of the Abu Sayyaf terrorist group and the self-described emir of ISIS in South-East Asia.
Lorenzana said a hostage held by the militants had led them to Hapilon and Omar Maute.
"She was able to confirm the presence of Isnilon and Maute in that particular building," he said.
"That's the building we assaulted this morning."
A video of the Maute brothers planning the tactics of the attack was released showing Hapilon at the table during a planning meeting.
The men said they were establishing an ISIS caliphate in South-East Asia.
The militants released videos of the execution of police officers captured in the early days of the battle.
Early attempts to clear the city by police and soldiers were repelled by militants, and the battle soon ground down into siege, with soldiers barely capturing any ground for weeks on end.
