"Je serai (ta meilleure amie)" is the name of a 2001 song recorded by the French singer Lorie.

It was released on 30 October 2001 as second single from her debut album Près de Toi, on which it features as third track.

It achieved success in Belgium (Wallonia) and France, but its sales and positions on charts were hugeless in comparison with those of the previous single, "Près de moi".

The song, who deals with the friendship between the singer and her best female friend, was composed and produced by Johnny Williams and Louis Element.
