The rampe de Laffrey (sometimes called the descente de Laffrey or the côte de Laffrey) is a section of France's Route nationale 85, itself part of the route Napoléon. It connects the communes of Laffrey and Vizille in the department of Isère, about 15 kilometers southeast of Grenoble.

This steep and mostly relatively straight section of road ends in a sharp turn, and it is known for the high number of fatal accidents that have occurred in this final curve. Four of them, in 1946, 1973, 1975, and 2007, involved buses of pilgrims returning from Notre Dame de la Salette, and are among the deadliest in French history.
