The march by the Cormeen Rising Sons of William Flute band will take place between 7.30pm and 9.30pm on Saturday.
It was given the go-ahead last week by the Parades Commission, despite opposition from nationalist politicians. The ruling was later upheld.
Thousands of people are expected to be in Armagh for the main St Patrick's parade, which will take place before the loyalist event.
In a statement, the PSNI said its officers will be on patrol throughout the day.
"I am aware of concerns from some groups in relation to a band parade scheduled to take place in the city on the evening of St Patrick's Day," said Chief Superintendent Alasdair Robinson.
"Previously this parade has taken place in Killylea but as numbers have grown the organisers have moved to bring it into the bigger venue of the city; similar to many other parades which take place without incident throughout the year.
I would ask all of those with influence in the community to work with us to ensure that all events are equally supported and respected throughout the course of the day.
Chief Superintendent Alasdair Robinson
Sinn Féin MP for the area Conor Murphy has appealed for calm ahead of St Patrick's Day.
"The decision to allow a loyalist band parade through Armagh on St Patrick's Day is flawed at the most fundamental level," Mr Murphy said.
"The PSNI and Parades Commission have said that they are satisfied that this parade is non controversial and while I do not believe this to be the case I would appeal to all those in Armagh tomorrow to remain cool headed."
Earlier this week, Cormeen Rising Sons of William Flute Band said they will fully comply with the determination of the Parades Commission.
Police say they hope this year's celebrations in Armagh can run as smoothly as they have in the past.
"As with all celebrations planned for St Patrick's Day we will provide appropriate support and assistance", Chief Superintendent Alasdair Robinson said.
