A number of paint bombs were thrown at Clifton Street Orange Hall, near Carlisle Circus in the north of the city, at around 7pm this evening.
It is the fifth time the hall has been attacked since July of last year.
Several meetings were taking place in the building – however, none were disrupted.
Belfast County Grand Master George Chittick condemned those responsible for the incident.
The senior Orangeman – who appealed for calm - claimed the attack was a “deliberate and obvious attempt to raise tensions” ahead of the Royal Black Institution’s Last Saturday parade in the area this weekend.
Mr Chittick also called on any witnesses to contact the police as a matter of urgency.
The Clifton Street incident is the 12th reported attack on Orange property so far this year and the third this month.
