A hall church is a church with a nave and aisles of approximately equal height. In England, Flanders and the Netherlands, it is covered by parallel roofs, typically, one for each vessel, whereas in Germany there is often one single immense roof. The term was invented in the mid-19th century by Wilhelm Lübke, a pioneering German art historian. In contrast to an architectural basilica, where the nave is lit from above by the clerestory, a hall church is lit by the windows of the side walls typically spanning almost the full height of the interior.
 In English language, there are two problems of terminology on hall churches:
 The first churches with naves and aisles of equal height were crypts. The first aisled hall church north of the Alps is St Bartholomew's Chapel (German: Bartholomäuskapelle) at Paderborn, consecrated c.1017.
In western France, there are some Romanesque hall churches with parallel barrel vaults. Poitiers Cathedral is considered to be the first Gothic hall church, and was probably an example for the Gothic hall churches of Westphalia. Most familiar was the construction of aisled hall churches in the late Gothic period, most notably in the areas of Westphalia and upper Saxony.
 In the Netherlands and Flanders, most hall churches have no stone vaults under one longitudinal roof, as is typical in Germany, but wooden barrel vaults with separate longitudinal roofs over each nave or aisle.
In England, there are more than a thousand aisled hall churches with wooden barrel or waggon roofs, as well as other kinds of ceilings (see Commons:Category:Hall churches in England by county), though official descriptions do not use the term hall church. In German literature on English medieval architecture, they are mentioned as a frequent type peripherally. 
 In Devon, more than 200 churches (or a part of a church) are such aisled halls, forming the majority of all church buildings, there. In parts of Wales, two-vessel halls are a traditional type of churches, as mentioned using terms like "typical two naves" in descriptions by Cadw. In Scotland, some aisled hall churches are Neoclassical buildings, and some aisled Gothic Revival hall churches have been built there transferring medieval English forms.
 There are also English hall churches vaulted with stone, such as Temple Church in London, the choir of Bristol Cathedral and the Lady Chapel of Salisbury Cathedral.
 Some Gothic Revival churches apply the hall church model, particularly those following German architectural precedents. One example of a neo-Gothic hall church is St. Francis de Sales Church in Saint Louis, Missouri, designed by Viktor Klutho and completed in 1908.
 A completely separate 20th-century usage employs the term hall church to mean a multi-purpose building with moveable seats rather than pews and a chancel area which can be screened off, to allow use as a community centre during the week.  This was particularly popular in Britain in inner city areas from the 1960s onwards.
