Auditorium Maurice-Ravel, Concert hall in Part-Dieu district, Lyon, France.

Auditorium Maurice-Ravel is a concert hall in the shape of a scallop shell, built of prestressed concrete in the Part-Dieu district. Its main room is fan-shaped, with light wood flooring, tiered seating and a stage of about 400 m². At the rear of the stage stands an organ with silver and white pipes, and the pale side walls hold vertical stacks of lit rectangular alcoves.

The National Orchestra of Lyon, founded in 1903, had no symphony hall and played at the Salle Rameau. Robert Proton de la Chapelle, musicologist and deputy for fine arts under mayor Louis Pradel, pushed for a new building; the municipal council approved it on 19 September 1971. After three years of works, the hall opened on 14 February 1975 with Serge Baudo conducting Berlioz and Ravel, with 18-year-old pianist Pierre-Laurent Aimard as soloist.

The building is named after Maurice Ravel, whose birth centenary fell in 1975, the year of the hall's opening. Its inaugural concert on 14 February 1975 featured the Orchestre national de Lyon under Serge Baudo in Berlioz's Symphonie fantastique and Ravel's Daphnis et Chloé Suite No. 2 and Piano Concerto in G, with 18-year-old Lyon pianist Pierre-Laurent Aimard as soloist. A weekend of festivities followed, with choirs, recitals and symphonic concerts.

The hall stands on Place Charles-de-Gaulle at the south-east corner of rue Garibaldi and rue de Bonnel, beside the Part-Dieu tower and shopping centre. The concert room is on the first floor, reached through a ground-floor atrium with shops and exhibitions. The 400 m² stage and 2,120 seats mean latecomers wait outside until a break.

The organ was built by Aristide Cavaillé-Coll for the 1878 Exposition Universelle, moved to the Palais de Chaillot in 1939, and installed in Lyon by Georges Danion in 1977. It has 82 stops, 121 ranks and 6,508 pipes, and until 2016 it was the only large concert-hall organ in France.
