The Renault Clio () is a supermini car (B-segment), produced by French automobile manufacturer Renault. It was launched in 1990, and entered its fifth generation in 2019. The Clio has had substantial critical and commercial success, being consistently one of Europe's top-selling cars since its launch, and it is largely credited with restoring Renault's reputation and stature after a difficult second half of the 1980s. The Clio is one of only two cars, the other being the Volkswagen Golf, to have been voted European Car of the Year twice, in 1991 and 2006.

The car is named after Clio, one of the nine Muses in Greek mythology. In Japan, it is sold as the Renault Lutecia because Honda retains the rights to the name Clio after establishing the Honda Clio sales channel in 1984. Lutecia is derived from the name of Lutetia, an ancient Roman city that was the predecessor of Paris. The Renault Lutecia was formerly available through Yanase Co., Ltd., but in 1999 Renault purchased a stake in Japanese automaker Nissan. Following Renault's takeover, distribution rights for the Lutecia were handed over to Nissan locations in 2000 and sold at Nissan Red Stage locations.
