Erinsborough is a fictional suburb of Melbourne, Australia, where the soap opera Neighbours is set, focusing on the domestic and professional lives of the people who live and work there. Neighbours primarily centers on the residents of Ramsay Street and other Erinsborough locations, most prominently those situated within the Lassiters complex. Erinsborough is a loose anagram of Neighbours.

Neighbours is an Australian television soap opera, which has aired since 18 March 1985. It was created by television executive Reg Watson. The Seven Network commissioned the show following the success of Watson's earlier soap Sons and Daughters. Although successful in Melbourne, Neighbours underperformed in the Sydney market and was cancelled by Seven four months after it began airing. It was immediately commissioned by rival Network Ten for a second production season, which began screening on 20 January 1986. Neighbours became the longest-running drama series in Australian television history. In 2005, it was inducted into the Logie Hall of Fame.
