Heinrich Ignaz Franz von Biber (August 12, 1644 - May 3, 1704) was a Bohemian composer and violinist.

He was born in Wartenberg (now Stráž pod Ralskem, Czech Republic). In 1684 he became Kapellmeister in Salzburg, where he died twenty years later.

His prolific works show a predilection for canonic use and harmonic diapason that pre-date the later Baroque works of Johann Pachelbel and Johann Sebastian Bach. He was known as a violin virtuoso and is best known for his violin works, many of which employ scordatura (unconventional tunings of the open strings). He wrote much choral and chamber music, concerti, operas and a number of more well-known pieces such as the "Nightwatchman" Serenade and "Harmonia Artificiosa."
