“Jessie’s Girl” is a song written and performed by Australian singer Rick Springfield. It was released on the album Working Class Dog. The song is about unrequited love, and centers on a young man in love with his best friend’s girlfriend.

Upon its release in the United States in 1981, the song was slow to break out. It debuted on Billboard’s Hot 100 chart on 28 March but took 19 weeks to hit No. 1 reaching that position on 1 August, one of the slowest climbs to number one at that time. It remained at No. 1 for two weeks and would be Springfield’s only No. 1 hit. The song was at No. 1 when MTV launched on 1 August 1981. Billboard ranked it as the No. 5 song for all of 1981.

The song also peaked at No. 1 in Springfield’s native Australia and later won Springfield a Grammy Award for Best Male Rock Vocal Performance.

The song was released in the United Kingdom in March 1984 and peaked at number 43 on the UK Singles Chart in April 1984.

Springfield recorded an acoustic version of the song for his 1999 album, Karma.
