A post town is a required part of all postal addresses in the United Kingdom, and a basic unit of the postal delivery system. Including the correct post town in the address increases the chance of a letter or parcel being delivered on time. Post towns in general originated as the location of delivery offices. Currently their main function is to distinguish between locality or street names in addresses not including a postcode.

There are approximately 1,500 post towns which are organised by Royal Mail subject to its policy only to impose changes where it has a proven, economic and practical benefit to the organisation, covering its own cost. Each post town usually corresponds to one or more postal districts (the first part of the postcode) therefore each post town can cover an area comprising many towns, urban districts and villages. Post towns rarely correspond exactly to administrative boundaries and their associated physical features. As such they often group a small minority of neighbourhoods, streets or houses together with a main settlement in a different county, area of local government or administration (including healthcare trust), constituency, European statistical region and/or traditional parish. This was a main reason why postal counties were abolished (but not prohibited) in 1996.

In some places several post towns cover a single postal district (with each post town corresponding to one or more of its postcode sectors). There are anomalies where post towns and postcode sectors have a more unusual co-relation. For example, the postcode sector EH14 5 is split between three post towns: Juniper Green, Currie and Balerno. Its other postcode sectors are generally one of these, Balerno.

The Royal Mail states that the post town must be included on all items and should be clearly written in capitals.

The use of postcodes means that it is no longer necessary to include the former postal county in a postal address. Some post towns, known as special post towns, never required the inclusion of a postal county, either because the town was large or because it gave its name to the county.
