Piano Concerto No. 3 in D minor, Op. 30 is a piano concerto by Russian composer Sergei Rachmaninov, composed and premiered in 1909. It is a late-Romantic work that features highly virtuosic, densely textured piano writing alongside sweeping orchestral sonorities, representing a culmination of Rachmaninov's concerto style and a central, technically demanding work in the piano concerto repertoire.
