6 is a historic former fire station at 284 Center Street in Bangor, Maine.

The building was listed on the National Register of Historic Places on April 7, 1988.

6 is located in a predominantly residential area north of downtown Bangor, at the northwest corner of Center and Montgomery Streets.

It is a rectangular two story building, built out of brick and stone, and topped by slightly flared hip roof with the square base of a now-removed cupola at its center.

The first-floor street-facing openings are set in rounded-arch openings, with two former equipment bay entrances facing Center Street, and a central pedestrian entrance bay facing Montgomery.
