A corn exchange is a building where merchants trade grains. The word "corn" in British English denotes all cereal grains, such as wheat and barley; in the United States these buildings were called grain exchange. Such trade was common in towns and cities across England until the 19th century, but as the trade became centralised in the 20th century many such buildings were used for other purposes. Several have since become historical landmarks.

Aylesbury Town Hall is a name which has been used for two different buildings in Aylesbury, Buckinghamshire, England. Since 2007 the name has been used for an office building at 5 Church Street, which serves as the headquarters of Aylesbury Town Council. The name was also formerly used for a complex of buildings which had been built in 1865 as a corn exchange in Market Square, and which served as the offices and meeting place of the local council from 1901 to 1968. The majority of the old town hall was demolished shortly afterwards, leaving only the entrance archway facing Market Square still standing, now called Town Hall Arches. This remaining part of the old town hall is a Grade II* listed building as part of the range of civic buildings on the southern side of Market Square including the old County Hall.
