Gaer ({{langx|cy|Y Gaer}}) is a community and electoral district ("ward") of the city of Newport, South Wales.

The ward includes both the Gaer and Maesglas estates but does not include Ebbw Bridge. To the south west of the ward is a listed monument known as the Gaer Hillfort (alternative: the Gollars) a large ancient hill fort and defensive position overlooking the Ebbw River with views south across the River Severn to England and north towards Twmbarlwm and Mynydd Machen. It is believed to date to the Iron Age.{{cite book|last=Preece|first=Jan|title=Newport Through Time|url=https://books.google.com/books?id=aOJiCgAAQBAJ&pg=PT68|date=15 September 2015|publisher=Amberley Publishing Limited|isbn=978-1-4456-3983-3|page=68}}{{cite book|title=An Inventory of the Ancient Monuments in Glamorgan: Volume III: Medieval secular monuments.
