"Modern Girl" is the debut single by Scottish pop singer Sheena Easton. The song was originally released in February 1980, reaching #56 in the UK charts, before being re-released to top ten success in August of the same year. The song would also go on to reach the US top 20, when it was released in 1981 as her second single, following the #1 hit "Morning Train (9 to 5)".

Exposure on the BBC television production The Big Time not only resulted in a record deal with EMI, but also pushed Easton's 1980 debut singles, "Modern Girl" and " 9 to 5," into the UK top ten. Her debut LP, Take My Time, followed in January 1981.

In the US, "9 to 5" was released in February 1981 under the title "Morning Train", to avoid confusion with Dolly Parton's recent hit of the same name; regardless, the single topped the U.S. pop charts. "Modern Girl" was then released as the second US single in May and peaked at #18 in July.
