A potential London NFL franchise is a hypothetical National Football League (NFL) American football team based in London, formed as a new expansion team or by relocating one of the existing 32 NFL teams currently based in the United States. Should the league establish a team in London, it would become the first of the major professional sports leagues in the United States and Canada to establish a franchise outside either of those two countries.

A London NFL franchise would be intended to grow the league's revenues and provide further access to the British and European markets. However, the agreement of league owners is needed to undertake an expansion or relocation, and a London franchise would face financial, legal and logistical challenges. Possible home stadiums for the London team include one or more of Wembley Stadium, Twickenham Stadium or Tottenham Hotspur Stadium.

Since 2007, the league has held multiple regular season games in London each season as part of NFL London Games, allowing the league to test solutions to some of the challenges facing a hypothetical London franchise.
