"Il faut laisser le temps au temps" is a 1990 song recorded as a duet by the French singers Didier Barbelivien and Félix Gray.

Written by Barbelivien, while the music was composed by Gray, this ballad was released in November 1990 and became the second single from their 1991 album Les Amours cassées.

It hit number one on the single chart in France, and was also a success in the French-speaking part of Belgium.

In France, "Il faut laisser le temps au temps" debuted at number 18 on the chart edition of 1 December 1990, which was the highest debut that week.

[2] "Il faut laisser le temps au temps" reached a peak of number four on the Belgian (Wallonia) chart, on 22 December 1990,[3] thus failed to match the massive success of "À toutes les filles...", the duo's previous single, which was number one.
