Dr. techn. Per Brinch Hansen (13. november 1938 på Frederiksberg – 31. juli 2007) var en dansk datalog og i årene 1987-2007 professor ved Syracuse-Universitetet i New York.

Per Brinch Hansen var en af pionererne inden for udvikling af parallelprogrammering og principper for styresystemkerner. Han var også ophavsmand til det danske ord for computer: Datamat.

I 1960'erne arbejdede Per Brinch Hansen på Regnecentralen, først i compilergruppen under Peter Naur og Jørn Jensen, sidenhen som chefarkitekten bag RC4000-datamaten og dens banebrydende operativsystemkerne. I 1972 skrev han den første bog om Operating System Principles.^[1]

I perioden 1970-2000 gjaldt det parallelprogrammering og datalogi: Inspireret af Ole-Johan Dahl og Kristen Nygaards programmeringssprog Simula 67 opfandt han monitorbegrebet i 1972. I USA udviklede han det første parallelle programmeringssprog, Concurrent Pascal i 1975, og skrev i 1977 den første bog om parallel programmering: The Architecture of Concurrent Programs.^[2]

I de seneste år dokumenterede Brinch Hansen den historiske udvikling inden for disse centrale emner.
