The Barton-upon-Humber Assembly Rooms is a Grade II listed building in Barton-upon-Humber, North Lincolnshire, opened in 1843 as a Temperance Hall.

The building is two storeys in height and is built from local, red bricks capped with a Welsh slate roof. On the Queen's street frontage it has a central 6-panel door under an oblong fanlight within a pilastered doorcase with projecting cornice. This main entrance is flanked by two additional doorways, each a 4-panel door beneath an oblong fanlight. There are sashed windows with sixteen panes on the ground floor and twenty-four panes on the first floor. Each window has a channelled and cambered stone lintel with a larger central keystone. Above the first floor windows are recessed brick panels. At the top of this frontage, there is a stepped brick cornice. A stone plaque above the main door is carved with the words 'Assembly Rooms'. To the left of this is a blue plaque recording its construction as a Temperance Hall in 1843.

The building was constructed in 1843 as a Temperance Hall at a cost of £700 following the formation of a Temperance Society in Barton in 1837. In 1903 the building was closed and offered for sale. In it was re-opened as the Assembly Rooms.

It is currently used as the offices for Barton Town Council.
