Surfer is an integrated advertising campaign launched in 1999 by Diageo to promote Guinness-brand draught stout in the United Kingdom.

The cornerstone of the campaign is a television commercial, originally 60 seconds long, which centred on a Polynesian surfer successfully taking on a gigantic wave.

[3] The plot centers on a group of surfers, waiting for the perfect wave.

The text also draws inspiration from Herman Melville's novel Moby Dick, including the line "Ahab says, 'I don't care who you are, here's to your dream.'"

An extended 90-second version is available on the 2005 DVD The Work of Director Jonathan Glazer.
