Ultimate Manilow is a greatest hits album by Barry Manilow, released in 2002. Nearly every top 20 hit is included in this collection. This compilation is best known for setting the stage for a comeback for Manilow, as it debuted at No. 3 on the charts. While on a six-week tour to promote his latest album Here at the Mayflower, Manilow immediately extended it to a six-month tour. At the time Ultimate Manilow was released, no other compilations of Manilow's music were in print.

Ultimate Manilow, with a slightly different track listing (but with the same number of tracks), was also issued in the United Kingdom in 2004, charting first in March of that year.
