The 20-year-old midfielder has been scouted by Arsenal and Newcastle, two English sides well established in the French transfer market.
But Thauvin has opted instead to join 2011 Ligue 1 champions Lille on a four-and-a-half year deal which will see him remain at Stade Armand Cesari on loan until the summer.
"I am very pleased to join Lille," he told Lille's website.
"Lille offered me a beautiful sporting project, and I immediately liked it and with the support of my advisors we agreed straight away."
