A Welcome To Britain (retitled How to Behave in Britain) is a 1943 training film for the United States Armed Forces which was narrated (and co-written and co-directed) by Burgess Meredith and Anthony Asquith.

The film explains to United States troops being deployed to Europe for the invasion of Normandy how they should act and behave in the United Kingdom. It demonstrates appropriate behaviour and depicts what is expected in given social situations. Though produced for American viewing, the film was produced by the UK's Ministry of Information through the Strand Film Company, which specialized in making documentaries in the 1930s and '40s. It was co-written by the Hollywood writer Sam Spewack, who came to Britain with Meredith.
