Anton Rubinstein, himself a renowned pianist, left five numbered piano concertos. (He wrote three earlier piano concertos; two were lost and the third was transformed into Octet, Op. 9.) Rubinstein composed the Fourth Concerto in 1864. He published two revisions of it and then a final revision in 1872. He dedicated the concerto to the violinist Ferdinand David.

The concerto is in three movements:

1. Moderato assai
2. Andante
3. Allegro
