"Get the Party Started" is a song by American recording artist Pink, and was the first single from her second album titled Missundaztood (2001). It became an international hit and reached the top ten in many countries. The song was Pink's biggest-selling song at that time. The track was released on October 9, 2001 to positive reviews from critics and after the release of the single it was confirmed that Pink would be releasing Missundaztood.

The song was composed by former 4 Non Blondes frontwoman, Linda Perry. She said that the process of making the song was "so unlike me"; according to her, she was going through a "weird phase" during which she wanted to learn how to program drums. She programmed her first beat, picked up a bass guitar, and, in her words, "did what the beat was asking me to do." She decided to put "every wrong instrument" in the song, and consequently acquired a horn sample. "I was doing the music, the melody was already coming to me in what I wanted the song to be," she said. She finished the song by including in the song "every catch phrase you possibly could imagine", before laughing at the realization that she had written a potential hit single and her first dance song. "You create something in your bedroom or your house, and it's just a fun thing that you're doing," she said. "Then all of a sudden, you hear that song that you started in your house, and it's on the radio. And people are now acknowledging it. It's just trippy."

The song reached number four on the U.S. Billboard Hot 100 on December 29, 2001, becoming one of Pink's biggest solo hits in the U.S. with "Most Girls" also reaching number four on the Billboard Hot 100 in 2000 and "So What", "Raise Your Glass", and "Just Give Me a Reason" reaching number one in 2008, 2010, and 2013 respectively, and "Fuckin' Perfect" that reached number two in America. It peaked at number two in the UK, where it was narrowly denied the top spot by the posthumous release of George Harrison's "My Sweet Lord". It reached number-one in Australia and number-two in many European countries most notably Austria, Germany, Italy and Switzerland, being held off from the top position by Shakira's smash hit "Whenever, Wherever". "Get the Party Started" was certified gold in Australia, Austria, Germany, France Sweden and Switzerland, and in Norway it received a platinum certification. The song was nominated for a Grammy Award in 2003 in the category of "Best Female Pop Vocal Performance", which it lost to Norah Jones's "Don't Know Why". It won the award for "Favorite Song" at the Kids' Choice Awards of 2002, and at the MTV Europe Music Awards of 2002 it won the award for "Best Song". "Get the Party Started" is often considered one of Pink's signature songs as she tends to finish her shows with this song in her encore section along with a ballad song such as "Nobody Knows" and "Glitter In The Air". In December, the song was listed as number 81 on Rolling Stone's Top Songs of the 2000s.
