Antonio Janigro (21 January 1918 – 1 May 1989) was an Italian cellist and conductor.
Born in Milan, he began studying piano when he was six and cello when he was eight. Initially taught by Giovanni Berti, Janigro enrolled in the Verdi Conservatory of Milan, where he was instructed by Gilberto Crepax. By 1934 Janigro was studying under Diran Alexanian and Pablo Casals at the École Normale in Paris. He graduated from the school in 1934 and began performing solo and in recitals with Dinu Lipatti, Paul Badura-Skoda and Alfredo Rossi.
An unfortunately timed vacation in Yugoslavia left Janigro stranded in that country for the duration of World War II. He became a professor of cello and chamber music at the Zagreb Conservatory, where his influence developed modern cello playing in Yugoslavia. He also performed as part of the Maček-Šulek-Janigro Trio. At war's end Janigro travelled throughout South America and the Far East as a soloist. In 1959, he was Fritz Reiner's soloist, along with Milton Preves and John Weicher, in a renowned Chicago Symphony Orchestra recording of Strauss's Don Quixote.
An extraordinarily gifted teacher, Janigro educated many cellists around the world. Most of them studied at the Staatliche Hochschule für Musik und Darstellende Kunst Stuttgart and the Mozarteum Salzburg. Among his students were Julius Berger, Mario Brunello, Thomas Demenga, Michael Flaksman, Michael Groß, Antonio Meneses, Andrej Petrac, Mario de Secondi, Giovanni Sollima, Gustavo Tavares, Enrico Dindo and Christoph Theinert.
