The Levallois technique is a name given by archaeologists to a distinctive type of stone knapping developed by precursors to modern humans during the Palaeolithic period.

It is named after nineteenth century finds of flint tools in the Levallois-Perret 48°53′40″N 2°17′18″E / 48.89444°N 2.28833°E / 48.89444; 2.28833 suburb of Paris in France. The technique was more sophisticated than earlier methods of lithic reduction, involving the striking of flakes from a prepared core. A striking platform is formed at one end and then the core's edges are trimmed by flaking off pieces around the outline of the intended flake. This creates a domed shape on the side of the core, known as a tortoise core as the various scars and rounded form are reminiscent of a tortoise's shell. When the striking platform is finally hit, a flake separates from the core with a distinctive plano-convex profile and with all of its edges sharpened by the earlier trimming work.

This method provides much greater control over the size and shape of the final flake which would then be employed as a scraper or knife although the technique could also be adapted to produce projectile points known as Levallois points.
