The London Suite, also known as London Everyday, is a suite of orchestral music written by the English composer Eric Coates in 1933.

It consists of three movements:

I. Covent Garden (Tarentelle)
II. Westminster (Meditation)
III. Knightsbridge (March)

The work was extremely popular when it was first published, no doubt helped by part of the third movement, Knightsbridge, being used as the theme tune for a BBC Radio chat show programme called In Town Tonight.
