The incident happened in a car park close to the Coastguard station in the Quay Street area of the town centre.
Police said the attack happened sometime between 11pm on Friday and 1.30am on Saturday.
They have appealed for information and are particularly keen to talk to a woman living in the area who helped the "distressed" victim following the incident.
They are also asking for anyone who saw suspicious activity surrounding a blue four-door car in the area to contact Bangor police.
North Down Mayor Andrew Muir said: "I am appalled that yet another attack has taken place in Bangor. My thoughts are with the victim after what must have been a terrifying ordeal.
"Attacks like these send shock waves through the local community and I would appeal for anyone with information on the perpetrator to come forward and speak to the PSNI immediately.
The Alliance councillor added: "We must ensure our streets are safe and I would also encourage all local residents to remain vigilant and to take the correct precautions to secure their safety when out and about late at night."
It is the latest in a series of sex attacks in the seaside town.
