In a Perfect World... is the debut studio album of American R&B and pop singer-songwriter Keri Hilson, released on March 24, 2009 on Zone 4. Originally planned for a 2007 release, it was pushed back numerous times into 2009, amid her label's budget issues and minor single releases. Production for the album was handled primarily by Timbaland, Polow da Don, and Danja.

The album debuted at #4 on the U.S. Billboard 200 chart, selling 94,000 copies in its first week. On October 22, 2009, it was certified gold by the Recording Industry Association of America, following shipments in excess of 500,000 copies in the United States. The album earned Hilson Grammy Award nominations for Best New Artist and Best Rap/Sung Collaboration in 2010.

"Energy" was released as the first single (except Europe) and was available as a digital download on May 27, 2008. The video premiered on July 14, 2008. It charted at number 78 on the Billboard Hot 100, number 21 and 72 on Hot R&B/Hip-Hop Songs and Pop 100 respectively. The single performed best in New Zealand where it charted at number 2 but failed to significantly chart elsewhere. Hilson announced in July 2009 that the single would be re-promoted as the next international single following the success of "Knock You Down". It was released in the UK as a download on September 13, 2009 and a CD single on September 14. It peaked at number 45 in the UK. Blender magazine ranked it number 61 on its list of the "The Top 144 Songs of 2008".

"Return the Favor" was released officially as the second worldwide single on October 7, 2008 and the video, premiered on October 23, 2008. It failed to chart in the U.S. It was subsequently released in the UK and Europe as the lead single. The video was released to UK music channels on March 16, 2009 and received good airplay on UK radio. The song charted at number 83 before peaking at 19.

"Turnin' Me On" featuring Lil Wayne was released as the third single (not released in Europe) on November 25, 2008. The single became Hilson's most successful solo offering at the time as it peaked at number 15 on the Billboard Hot 100, number 2 and 28 on the U.S. Hot R&B/Hip-Hop Songs and Pop 100 respectively. It was also the first single to chart in Canada although it did only reach number 80. Vibe magazine named it the sixty-seventh best song of 2008.

"Knock You Down" featuring Kanye West & Ne-Yo is the fourth single from the album (first for Latin America and second for Europe). The video was premiered on March 23, 2009 on Ne-Yo's official YouTube channel. The single is Hilson's best solo release to date reaching number 3 on the Billboard Hot 100 and 1 on the U.S. R&B/Hip-Hop chart. It has already been released as the second single in Europe and so reached number 5 on the UK Top 40 and number 2 on the UK R&B Chart.

"Slow Dance" is the fifth single (not released in Australia) from the album. Two videos were shot, one in July 2009 with director Paul Hunter, and one in August 2009 with director Chris Robinson. Since July 13, 2009 the single has been serviced to both Rhythmic and Urban radio stations in the US, but has yet to make any impact on the charts.

"I Like" is a song recorded in 2009 and added to the German re-release of the album, In a Perfect World.. I Like Edition. It was released as the third single in Europe (sixth overall), and appears on the soundtrack to the German film Zweiohrküken. It was released in the UK on March 29, 2010. It was released as the fifth single in Australia on November 25, 2009.
