Graffiti was discovered daubed on the arch in the Antrim Road area at 12.20pm on Tuesday.
It comes ahead of the annual mini-Twelfth parade set to take place through the town later.
Carnmoney District Master Albert Steele has condemned the incident.
He said: "The people who did this have no respect or tolerance for a differing viewpoint and it is a clear attempt to up the ante ahead of the Twelfth celebrations.
"Those responsible will not prevent us from expressing our cultural and Orange heritage."
The Orange Order said several hundred of its members will participate in the parade.
Police have called for anyone who witnessed the painting of the graffiti to come forward.
