Hans Haug (27 July 1900 in Basel – 15 September 1967 in Lausanne) was a Swiss composer and conductor, mainly of operas and theatrical music.
After short-term engagements as conductor in Grenchen and Solothurn, he became Second 'Kapellmeister' at the municipal orchestra and the theatre of Basel (1928–1934).
In the years following World War II, he resumed an international conducting career and also his compositional interest in opera.
He took guitar lessons on a regular basis with José de Azpiazu from October 1953 to January 1954 in order to learn more about the instrument.
In 1963, his Capriccio for flute and guitar was written for the duo Werner Tripp and Konrad Ragossnig (released on RCA Victor 440.182).
