The Sonatina in G major is a composition for solo piano attributed to Ludwig van Beethoven (listed as Anh. 5 No. 1 in the Kinsky–Halm Catalogue). The work was published in Hamburg, Germany, after Beethoven's death; its authenticity is doubtful, as it uses styles never seen by Beethoven before.
The composition is in two movements:
The first movement is in times; the second movement is titled Romance and is in time.
