"Je ne sais pas pourquoi" (English: "I Do Not Know Why"), also known as "I Still Love You (Je ne sais pas pourquoi)" in Australia and New Zealand, is a song by Australian recording artist and songwriter Kylie Minogue from her debut studio album Kylie (1988). Released as a single on 10 October 1988 by PWL, the song has subsequently appeared on most of Minogue's hits compilations including Greatest Hits (1992), Ultimate Kylie (2004) and, most recently, Step Back in Time: The Definitive Collection, released in 2019. Like most of Minogue's material between 1988 and 1992, it was written and produced by Stock Aitken Waterman.

Kylie is the debut studio album by Australian recording artist Kylie Minogue, released on 4 July 1988 by Mushroom Records. Minogue had established herself as a child actress before signing to the record label in early 1987. The success of her debut single, "Locomotion", resulted in her working with Stock Aitken Waterman, who produced the album and wrote nine of its ten tracks. Their recording sessions, commencing in October 1987 in London and Melbourne, coincided with Minogue's filming schedule for the soap opera Neighbours.
