Line D ({{lang|fr|Ligne D}}) is a rapid-transit line on the Lyon Metro. It runs east–west underneath the two major rivers of Lyon, France, connecting Vieux Lyon with the Presqu'ile and the Part-Dieu region. Line D commenced operation under human control on 4 September 1991, between Gorge de Loup and Grange Blanche. It was extended from Grange Blanche to Gare de Vénissieux on 11 December 1992, when it switched to automatic (driverless) operation, also known as MAGGALY (Métro Automatique à Grand Gabarit de l’Agglomération Lyonnaise). On 28 April 1997, the line was extended from Gorge de Loup to Gare de Vaise.

Being the deepest of the lines in Lyon, it was constructed mainly using boring machines and passes under both rivers, the Rhône and the Saône.
