The Sunday Night Project is a British comedy-variety show by Princess Productions that first aired on Channel 4 in February 2005 under the title The Friday Night Project. Originally broadcast on Friday nights, the show moved to Sunday nights for its seventh series in 2008.

Each week, the regular hosts (from series 2 onwards) Justin Lee Collins and Alan Carr are joined by a celebrity guest host. These guests provide an opening monologue, are interviewed by Alan and Justin and take questions from the studio audience. They also take part in comedy sketches, hidden camera stunts and a game show where someone from the audience is selected to win prizes.

When the show was called The Friday Night Project, it was not live: it was recorded at The London Studios on the night before broadcast on Channel 4. When the show became The Sunday Night Project, the Thursday-night taping schedule was retained.
