Peter Ilsted (14 February 1861 – 16 April 1933) was a Danish printmaker and painter. He was most associated with domestic interior scenes.

d created intriguing interior scenes which saw him form part of what was known as the ‘Copenhagen Interior School.’ Often overshadowed by his brother-in-law and great friend Vilhelm Hammershøi (1864-1916), Ilsted’s works possess their own dynamism, and his production of mezzotint prints were revolutionary for their use of the ‘à la poupée’ method.
