"Tha 'Ne Erotas" (Greek script: "Θα 'ναι έρωτας", English translation: "It Will Be Love") was the Cypriot entry in the Eurovision Song Contest 1999, performed in Greek by Marlain.
The song was performed fourteenth on the night (following Iceland's Selma with "All Out Of Luck" and preceding Sweden's Charlotte Nilsson with "Take Me to Your Heaven"). Despite being a favourite to win it only received 2 points (all from UK), placing 22nd in a field of 23, beating only Spain.
The song is a ballad, with Marlain singing about how to ensure that one's lover returns the feelings.
It was succeeded as Cypriot representative at the 2000 Contest by Voice with "Nomiza".
