Robert Henry Sorgenfrey (August 14, 1915 – January 7, 1996) was an American mathematician and Professor Emeritus of Mathematics at the University of California, Los Angeles. The Sorgenfrey line and the Sorgenfrey plane are named after him; the Sorgenfrey line was the first example of a normal topological space whose product with itself is not normal.

has abstract	Robert Henry Sorgenfrey (* 14. August 1915; † 7. Januar 1996) war ein US-amerikanischer Mathematiker. Robert Sorgenfrey begann 1933 das Studium der Mathematik und Physik an der University of California, Los Angeles (UCLA).

Nach weiteren Studien an der University of Texas at Austin kehrte er 1942 nach Westwood zurück; seine gesamte weitere akademische Karriere erfolgte an der UCLA, wo er 1979 emeritiert wurde. Mittels der nach ihm benannten Sorgenfrey-Geraden und Sorgenfrey-Ebene erzielte er das topologische Resultat, dass Produkte normaler Räume im Allgemeinen nicht wieder normal sind.
