Elly Ney (27 September 1882 – 31 March 1968) was a renowned German pianist celebrated for her interpretations of Ludwig van Beethoven's works. Born in Düsseldorf, Germany, she was introduced to Beethoven's music by her grandmother, which deeply influenced her musical direction. Ney studied at the Cologne Conservatory under Isidor Seiss and Karl Bötcher, and later in Vienna with Theodor Leschetizky and Emil von Sauer. Her career began to flourish after winning the Mendelssohn Scholarship in 1901.

Ney made her debut in Vienna in 1905 and became known for her profound and noble interpretations of Beethoven, as well as for her performances of works by Brahms, Schumann, and Mozart. She recorded extensively, with her rendition of Beethoven's Piano Sonata Op. 111 being particularly acclaimed.

Throughout her career, Ney was associated with several ensembles, including the Elly Ney Trio. She was awarded honorary freedom of the city of Bonn in 1927, recognizing her contributions to music.

However, Ney's legacy is marred by her affiliation with the Nazi Party, which she joined in 1937. She was involved in Nazi cultural activities and held anti-Semitic views, which led to a stage ban in Bonn after World War II. Despite this, she was named Honorary Citizen of Tutzing in 1952, although this honor was revoked posthumously due to her Nazi affiliations.

Elly Ney was married twice, first to conductor Willem van Hoogstraten, with whom she had a daughter, and later to Paul Allais. She passed away in Tutzing, Bavaria, in 1968. Her contributions to classical music, particularly her Beethoven interpretations, remain significant, though her political affiliations continue to cast a shadow over her legacy.
