The Piano Sonata No. 19 in G minor, Op. 49, No. 1, and Piano Sonata No. 20 in G major, Op. 49, No. 2, are short (and are considered relatively simple sonatas by some pianists) by Ludwig van Beethoven, published in 1805 (although the works were likely composed several years earlier). Both works are approximately eight minutes in length, and are split into two movements. These sonatas are referred to as the Leichte Sonaten to be given to his friends and students.
