Resan (Swedish for The Journey) is a 1987 documentary film by Peter Watkins, made between the years 1983 and 1985 on several continents, and structured around the theme of nuclear weapons, military spending and poverty. Ordinary people are asked about their awareness of these issues.

With a running time of fourteen hours and thirty-three minutes, Resan is the longest non-experimental film ever made. It was screened at the 1987 Festival of Festivals as well as the "International Forum for New Cinema" of the Berlin Film Festival in 1987, but has rarely been seen since. In February 2007, it was screened at the Mexico City International Festival of Contemporary Cinema (FICCO) as part of a retrospective on Peter Watkins. Between April 25 and May 1, 2007, all nineteen parts of the film were screened at the Austrian Filmmuseum in Vienna, Austria as part of a retrospective on Peter Watkins.
