The Hellmesberger Quartet or Hellmesberger Quartet (in English) was a string quartet formed in Vienna in 1849, founded by Josef Hellmesberger (father).

The original quartet was formed by Josef Hellmesberger as first violin, Carl Heissler as second violin, Matthias Durst as viola, and Carl Schlesinger as cello.

After 1860 there was a restructuring of the group, all its members being replaced, except the founder. Adolf Brodsky was the second violin until 1870, the year he left Vienna. Sigismund Bachrich became a viola. And David Popper would enter the group between 1868 and 1870 as a cello.

In 1875, [[Josef Hellmesberger (son) entered the quartet, as second violin, becoming the leader of the group in 1887.

Finally, Ferdinand Hellmesberger, son of Josef (father) and brother of Josef (son), joined the quartet as cello in 1883.

The quartet played an important role in the musical life of Vienna, playing quartets by Ludwig van Beethoven, Johannes Brahms, Franz Schubert, and Antonín Dvořák.
