Amalia Aurora Adelaïde Leuhusen, née Valerius (1 December 1828 – 1923), was a Swedish baroness, painter and concert singer.

In parallel, she studied singing as a student for Fanny Schäfer in Leipzig, and Ludwig Rellstab in Berlin.

In 1858, she married baron Axel Reinhold Leuhusen (1815–1886), and moved to Gothenburg, where she established herself as a singing teacher.

In parallel, she continued to make trips abroad to study art and singing in Germany and France.

The Finnish artist Albert Edelfelt was a family acquaintance and painted a portrait of Adelaïde Leuhusen in 1872.
