The Ultimate Collection (subtitled Celebrating Four Decades of Soul) is the fourth greatest hits album by Australian musician Renée Geyer.

Geyer's career has spanned four decades and has achieved commercial success, appearing on the Australian charts since the 1970s to 2000s.

[2] In a 2011 interview with Bendigo Weekly, Geyer said "People like it (the album) because it's the songs that I know are the most yelled out for me.

"[3] Julie Taylor from The Northern Advocate gave the album 3 out of 5 saying; "Her best known hit, Eddy Grant's "Say I Love You", is an essential, but somewhat out of place, inclusion in this collection of soulful classics.

There are also lighter moments with "Shaky Ground" and a cover of "Prince's "Thieves in the Temple".
