Halifax is a town in the metropolitan borough of Calderdale, West Yorkshire, England. It contains 254 listed buildings that are recorded in the National Heritage List for England. Of these, three are listed at Grade I, the highest of the three grades, 31 are at Grade II*, the middle grade, and the others are at Grade II, the lowest grade. The main industry of the town has been its cloth trade, which dates back to the 14th century, and grew particularly during the 19th century when the town increased considerably in size and prosperity. Of the listed buildings, there are relatively few dating from before the middle of the 18th century, with the great majority dating from between about 1825 and the end of the 19th century. There are many survivors from the cloth industry, especially mills that have been converted for other uses, particularly in the area of Dean Clough. A number of these former mills and associated structures are listed.
