Ultimate Collection is the second greatest hits album by British pop duo Eurythmics, released on 7 November 2005 by RCA Records.

The fact that the Ultimate Collection was closely connected to these reissues is also the chief reason for the omission of "Sexcrime (Nineteen Eighty-Four)".

Unlike 1991's Greatest Hits, Ultimate Collection contains two previous unreleased songs, "I've Got a Life" and "Was It Just Another Love Affair?

Ultimate Collection peaked at number five on the UK Albums Chart and has since been certified triple platinum by the British Phonographic Industry (BPI).

All tracks are written by Annie Lennox and David A. Stewart, except "When Tomorrow Comes" co-written by Patrick SeymourCredits adapted from the liner notes of Ultimate Collection.
