The Léner String Quartet, sometimes written the Lehner String Quartet, was a string quartet of Hungarian origin, founded in Budapest in 1918, which for most of its pre-war career operated in or from London. They appeared at the Royal Albert Hall, London on three occasions between 1922 and 1926. They also performed in New York, Amsterdam, and elsewhere in Europe. The Léner made the first complete recorded cycle of Beethoven quartets.
