Upwards of 17,000 members of the Royal Black Institution will be on parade at six locations across Northern Ireland for the traditional 'Last Saturday' demonstrations this weekend.
Around 350 preceptories, most accompanied by bands, will take part in processions in Comber, Antrim, Castledawson, Lisburn, Omagh and Aughnacloy.
Sovereign grand master Millar Farr, who will attend the Castledawson parade, said the Institution was once again looking forward to the much-anticipated day in the parading calendar.
He said: "The Last Saturday traditionally brings the curtain down on the loyal order parading season and we are expecting yet another magnificent finale.
"The various demonstrations will offer a wonderful spectacle of culture and pageantry, attended and enjoyed by large crowds at six different venues across the province.
"It has been a memorable and significant year for the Institution, perhaps most notable for our Christian ethos and our charitable outreach.
"We were delighted to present over £100,000 to Macmillan Cancer Support, with the substantive funds going towards a local aftercare scheme for prostate cancer patients. The Institution has also played a leading role in the ongoing commemorations in 2017 to mark the 500th anniversary of the Protestant Reformation."
Mr Farr added: "I trust and pray the respective Last Saturday demonstrations will be wonderful and memorable occasions for all involved."
