Sheena Shirley Easton (née Orr; born 27 April 1959) is a Scottish international recording artist and stage and TV/film actress. Easton first came into the public eye as the focus of an episode in the first British reality television programme The Big Time: Pop Singer, which recorded her attempts to gain a record contract and her eventual signing with EMI Records.

Easton's 1980 debut singles, "Modern Girl" and "9 to 5"," entered into the UK top ten, making her the first UK female artist to appear twice in the same top ten. In 1981, "9 to 5", topped the US Hot 100, making her the third UK female solo artist to achieve this, following Petula Clark and Lulu. In the US, the song was released as "Morning Train (9 to 5)".
