One of the smallest parades is the Clogher Valley demonstration.
The procession will once again have a cross-border element with brethren from Co Monaghan walking with local lodges.
Thirty lodges from three districts – Truagh, Fivemiletown and Annahoe – will take part in what is renowned as a family-friendly atmosphere.
The parade starts at Church Street at noon, proceeding to the demonstration field at Dungannon Road. County Grand Master James Emery will preside, with guest speaker deputy chaplain, Pastor Roy Graham.
