Garth Brooks in...the Life of Chris Gaines, also titled Greatest Hits, is an album by American country music artist Garth Brooks, in which Brooks assumes the fictitious persona of Australian rock artist Chris Gaines.

This album was purposely released a year in advance from the scheduled film release date to pique interest in Brooks performing rock instead of country.

The Lamb, however, was never filmed due to financial and management problems.

The track "It Don't Matter to the Sun" was later covered in 2005, by Rosie Thomas on her If Songs Could Be Held album, and later as a duet between Don Henley and Stevie Nicks on the Target edition of Henley's 2015 album Cass County.

On November 13, 1999, Brooks hosted Saturday Night Live as himself but performed the musical number ("Way of the Girl") as Chris Gaines without acknowledging to the audience that they were the same person.
