Mr Hume's remains were removed from his home in Donegal last night to St Eugenes's Cathedral in Derry.
Requiem mass will be celebrated by local priests and presided over by Bishop of Derry Donal McKeown, Archbishop of Armagh Eamon Martin and senior Anglican clergy starting at 11.30am
His family requested that mourners adhere to all Covid-19 guidelines ahead of the funeral and at the removal last night, when they asked people to light a candle for peace instead of lining the streets.
Mr Hume was prominent in the civil rights movement in the North before his long time commitment to achieving peace in Ireland through exclusively peaceful means.
In tributes from political leaders at home and abroad he was called "a hero, a political titan and a visionary".
It's understood the funeral will be a family one and they have hinted that a larger event to celebrate his life will be held at a later date.
