Richard Paul McGehee (* 20. September 1943 in San Diego) ist ein US-amerikanischer Mathematiker, der sich mit Dynamischen Systemen befasst, speziell aus der Himmelsmechanik. McGehee studierte am Caltech mit dem Bachelorabschluss 1964 und an der University of Wisconsin–Madison, wo er 1965 seinen Master-Abschluss machte und 1969 bei Charles Conley promoviert wurde (Homoclinic orbits in the restricted three body problem). Als Post-Doktorand war er am Courant Institute of Mathematical Sciences of New York University. 1970 wurde er Assistant Professor und 1979 Professor an der University of Minnesota in Minneapolis, wo er am Center for the Computation and Visualization of Geometric Structures war (von 1994 bis 1998 als Direktor).

In den 1970er Jahren führte er Koordinaten ein, mit denen er die Singularitäten bei Dreikörperstössen regularisierte. 1975 zeigte er mit John Mather, dass im kollinearen Vierkörperproblem Zweierstösse so akkumulieren können, dass sie ein Teilchen in endlicher Zeit ins Unendliche befördern. 1978 war er Invited Speaker auf dem Internationalen Mathematikerkongress in Helsinki (Singularities in classical celestial mechanics).

In the 1970s he introduced a coordinate transformation (now known as the McGehee transformation) which he used to regularize singularities arising in the Newtonian three-body problem. In 1975 he, with John N. Mather, proved that for the Newtonian collinear four-body problem there exist solutions which become unbounded in a finite time interval. In 1978 he was an Invited Speaker on the subject of Singularities in classical celestial mechanics at the International Congress of Mathematicians in Helsinki.

Na década de 1970 introduziu a transformação de coordenadas (conhecida atualmente como ) que usou para regularizar singularidades que surgem no problema dos três corpos newtoniano. Em 1975 provou, com John Mather, que para o problema newtoniano colinear dos quatro corpos existem soluções que tornam-se ilimitadas em um intervalo de tempo finito. Foi palestrante convidado do Congresso Internacional de Matemáticos em Helsinque (1978: Singularities in classical celestial mechanics).
