This is a list of compositions by the 20th-century Norwegian composer Geirr Tveitt. Since a sizable corpus of his works are lost, and since there are pieces that have been assigned an Opus number, but without names, pieces will be presented here as that.
| Name | Opus | Instruments/voices used | Notes | |
|---|---|---|---|---|
| Three sonatas for Solo Violin (lost) | 1 | Solo Violin | In and interview for NRK 14 February 1977, Tveitt claims that the first Opus wasn't for piano, but for violin. He mentions that his first Opus was "Two-part Slått for piano". "12 Two-part Inventions for piano" was published and is now known as Op. 1, most likely because it was his first work which was published. | |

| Aeolian Harp | 132 | Piano | Although a recording of Tveitt himself playing the piece exists, it differs radically from the only known, existent autograph score. It is possible that the recording is based on a later version of this piece which did not survive the fire, since the recording was made a few years after the score was completed. If this is true, then the final version of the piece is lost. | |
