"Top of the World" is a 1972 song written and composed by Richard Carpenter and John Bettis. It was a Billboard Hot 100 number-one hit for two weeks in 1973 for The Carpenters. Originally intended to be only an album cut for them, country music singer Lynn Anderson covered the song and was the first to release it as a single. Her version nearly topped the US Billboard Hot Country singles chart, reaching No. 2.

Originally recorded for and released on the duo's 1972 studio album A Song for You, the song topped the Billboard Hot 100 singles chart in late 1973, becoming the duo's second of three number one singles, following "(They Long to Be) Close to You" and preceding "Please Mr. Postman." Karen Carpenter re-recorded the song for the band's first compilation as she was not quite satisfied with the original.

In Japan, the song was used as the opening theme song for the 1995 Japanese drama Miseinen. In 2003, it was used for another drama, this time as the ending theme song for Beginner. It appeared on the 2010 soundtrack of Shrek Forever After when Shrek enjoys being a "real ogre" and terrifying the villagers, as well as in a prominent scene of the 2012 film Dark Shadows, with a performance by the Carpenters seen on a television screen.

Country music singer Lynn Anderson covered the song in 1973 for her studio album Top of the World, released on Columbia Records. It was the first single released from her album and her version of the song became the first hit. Anderson's cover reached No. 2 on the US country singles chart and No. 74 on Billboard Hot 100 in mid-1973. The success of Anderson's version prompted the Carpenters to release a new version as a single, where it topped the US pop singles chart for two weeks in December 1973. Anderson's cover was produced by her husband Glenn Sutton and Clive Davis. She later re-recorded the song for her 2004 album, The Bluegrass Sessions.
