InterCity is a name for the inter-city rail services in Europe.

In continental Europe, the word InterCity is used as a brand for certain long distance trains. These trains call at the major stations only; there are many more smaller stations served by local and regional trains only.

The term originated in the United Kingdom, with InterCity sector of British Rail. However, following privatisation, the term is no longer used there officially, although many people still refer to InterCity trains.
