Haukur Tómasson (born January 9, 1960) is an Icelandic composer. He has a Master's degree from the University of California, San Diego. He has also attended the Reykjavík College of Music, the Cologne University for Music and the Sweelinck Conservatory of Amsterdam. His earliest works (Octette and Eco del passato) used Fibonacci numbers to determine the intervals and durations. Later works such as Spiral, Strati and Offspring use a different approach based on his so-called "spiral technique". He also started to use Icelandic folk material in his compositions in the late 1990s.
