"Stay" is a song by UK based pop act Shakespears Sister, released by London Records in January 1992 as the second single from their album Hormonally Yours. Upon release, the single became a global smash hit becoming the duo's first and only No. 1 single in numerous territories, including the UK, where it topped the UK Singles Chart for eight consecutive weeks; the longest UK No. 1 reign for any all-female band, and was the fourth biggest selling single of 1992. The single also held the No. 1 position in band member Siobhan Fahey's birthplace, Ireland, for six weeks, and it was a transatlantic hit reaching No. 4 on the Billboard Hot 100 in the US.

At the 1993 Brit Awards "Stay" won the award for Best British Video. In November 2010, The X Factor contestant Cher Lloyd performed the song on series 7 of the show. Following this, the original version re-entered the UK, Ireland and the European Hot 100 Singles charts. The song originally sold 490,000 copies in the UK by the end of 1992 which was a year that saw low single sales, as of February 2012 it has sold over 600,000 copies (the threshold for a Platinum certification in the UK). As well as being used on The X Factor, the song has also been featured on Britain's Got Talent, Dancing on Ice, Strictly Come Dancing, The Voice of Ireland and The X Factor New Zealand.
