Sale of the Century (stylized as $ale of the Century) is an Australian game show that aired on the Nine Network from 14 July 1980 to 29 November 2001. It is based on both Great Temptation that aired from 1970 to 1974 and on the original Sale that first aired in the United States from 1969 to 1973. The Australian format of Sale has since been used internationally, including in a revived US version that aired from 1983 to 1989.

Tony Barber, the host of Great Temptation, was also the initial host of Sale for over a decade before being replaced by Glenn Ridge in 1991. Hostesses over the years have included Barbie Rogers, Victoria Nicolls, Delvene Delaney, Alyce Platt, Jo Bailey, Nicky Buckley and Karina Brown. Pete Smith was Sale's announcer for the majority of its run. Ron Neate was announcer for only the first ten episodes in 1980 before Smith took over.

From 30 May 2005 to 23 January 2009, the series was revived under its original Australian title, Temptation.
