The Tölzer Knabenchor, also known as the Tölz Boys' Choir, is a renowned boys' choir originating from Bad Tölz, Bavaria, Germany. It was founded in 1956 by Gerhard Schmidt-Gaden, who initially led a singing group from a scout group in Bad Tölz. The choir gained its name in 1957 during a parents' meeting. Initially focused on folk music, the choir quickly expanded its repertoire and began performing radio concerts on Bavarian Radio as early as 1956. The choir's first international tour took place in 1957, and by 1960, it had toured Luxembourg, France, England, and Belgium.

The choir became known for its participation in opera performances starting in the 1960s, with soloists performing in Mozart's "The Magic Flute" in 1964. Under the direction of Schmidt-Gaden, the choir was awarded the German Record Prize in 1973 for its performance of Johann Sebastian Bach's Christmas Oratorio. The choir has since toured globally, including destinations such as Chicago, China, Japan, Israel, Poland, and the USA. It has performed at prestigious festivals such as the Bayreuth Festival, Salzburg Festival, and Vienna Festival.

The Tölzer Knabenchor has collaborated with eminent conductors like Claudio Abbado, Daniel Barenboim, Leonard Bernstein, and Herbert von Karajan. The choir is also associated with a men's choir, ZwoZwoEins, composed of former members. The choir's headquarters are in Unterföhring near Munich, and it is currently led by Christian Fliegner. The choir continues to perform extensively, giving nearly 240 concerts and opera performances annually.
