Johann Andreas Streicher (13 December 1761 – 25 May 1833) was a German pianist, composer and piano maker. In 1793, he married Nannette Streicher (1769–1833), another piano maker and daughter of Augsburg piano maker Johann Andreas Stein. In 1794, they moved to Vienna. From that time, Streicher worked as a piano teacher and became increasingly known for his compositions. The Streicher piano-making business provided at least one fortepiano to Beethoven in his early years, of which the composer was fond, writing that it was "too good for me ... because it robs me of the freedom to produce my own tone".
