A cascaded micro-groove aerodynamic drag reducer is provided by creating a plurality of spaced-apart, microscopic grooves in the aerodynamic surface. Each of the grooves is defined by oppositely disposed side walls with each of the side walls of each groove having at least one catenary shaped surface provided thereon. In the preferred embodiment, each of the side walls is provided with a plurality of catenary shaped surfaces with each of the catenary shaped surfaces having a plurality of smaller catenary surfaces provided thereon.
