"Friends for Twenty Years" is the 4773rd episode of the Australian television soap opera Neighbours. The episode was written by Ben Marshall, directed by Jovita O'Shaughnessy, and executively produced by Ric Pellizzeri. It first aired on 27 July 2005 on Network Ten in Australia, as part of the soap's 20th anniversary. Planning for the episode began in March 2004, twelve months before the anniversary. Producers decided to celebrate the 20th anniversary on-screen in July, as winter ratings are usually higher.
