The Boe Galaxy is a Galaxy that exists in The Universe. It is named after the legendary Face of Boe, and consists of thousands of systems, many of which contain life. However, most of the Boe Galaxy's inhabitants are prehistoric, with only a few sentient races existing in the Galaxy as a whole. The economy is reliant on the Milky Way Galaxy and the League, and in return the League is allowed to use the planets of the Boe Galaxy for mining and research facilites. Apparently the Forerunners also visited this Galaxy at some point too.
