Antoine-Pierre de Bavier, also known as Antoine de Bavier and Anton von Bavier was a twentieth-century Swiss clarinettist and orchestral conductor. De Bavier was a pupil of the clarinetist Luigi Amodio and of Wilhelm Furtwängler. His earlier career was dedicated more particularly to his instrumental work as a clarinettist. He collaborated with the Végh Quartet in their early recording of the Brahms clarinet quintet, and was among the very few soloists to have worked and recorded with the Quartetto Italiano, with whom in 1952 he recorded the Mozart clarinet quintet. In 1956 he made a landmark recording of the Brahms clarinet sonatas.
